I compete in dressage at First Level. Thank you for asking. 
My best friend in high school rode English tack; not competitively, but I learned a little about it from hanging out with him. Interesting stuff.
I think you may be expecting a little too much from POF. From what I’ve heard of women’s experiences on dating sites, it’s common to receive a deluge of messages, often with nothing to indicate that the senders have even read your profile. (I don’t know if Plenty Of Fish has the same issue.) It’s hard to send the perfect introductory message. These guys at least made the effort to find something you’d expressed an interest in. I wouldn’t base an entire relationship on a fondness for old cars, but you could have gone to their profiles and seen if there was anything there that struck a chord with you. I think it takes a bit of effort on both sides to have a chance.
What’s so unusual about your job?
Oh, I went to their profiles and tried to find some other common ground. I spoke with several of them via the site’s message service and then by text and on the phone. I even met a couple of them. They were nice but kinda one-dimensional. What I’m whining about is that there’s more to me than a passing interest in car shows but none of them seemed interested in exploring it. Yes, I love horses, but I also have many other mainstream interests. Maybe it’s just unusual for a woman to mention in her profile that she likes cars.
I am an appellate court administrator. There are roughly 100 state appellate courts in the country (typically a Court of Appeals and a Supreme Court in each state) so there aren’t that many of us that do this kind of work. Most people don’t even know there are appellate courts in their state much less what is involved in the day-to-day running of one.
Mention that and get off of POF and at least on to OKC and the messages might start to back off a little. I’ve only glanced at POF (never set up a profile or anything) but it seems to be the state fair of the internet dating world.
If you mention the appellate court administrator that’ll at least give people a good way to start an email, but be prepared to answer the same question over and over and over (to anyone that you feel like replying to).
And as Robot Arm essentially said, it’s not fair to mention that you like car shows and then blame guys for mentioning it when they email you. I probably see the car show thing mentioned in less then one out of a hundred profiles (and it tends to be the pin up type girl), so I’m sure guys tend to go nuts when they see that. “OMG she’s into cars, I have to get an email to her before anyone else”.
Look at it this way, if you saw a guy that mentioned horse competitions amongst his interests and you emailed him about that, do you think it would be fair if he wrote back with “Is that the only thing about me you got out of my entire profile? I’ll take a pass”. Of course it’s not, it’s just the thing that caught your fancy.
If you don’t want people to email you about the car shows, don’t put it in your profile, but don’t be surprised when you find out that a lot more guys are into car shows then horse competitions or government work.
I agree, Joey P, that I probably need to get off of POF. As for removing the reference to car shows on my profile, that is exactly what I did. I took “car shows” off my list of interests and have not received a single message since. All I can assume is there are so many other attractive, slender, childless, drama-free women who like wine tasting, cooking, reading, hiking, concerts, art galleries, flea markets and going to the coast (let’s leave out the horses), that my profile just gets lost amongst all the others. 
I set up my profile and hardly mention anything. I figure less is more. Besides, since I’m a guy, I doubt anyone’s going to be messaging me. Really, that’s where the connection is made. Not what insignificant things you write in your profile.
With that being said, I kind of like OKCupid. I sort of go over-the-top romantic, but in a funny and charming way. Something that will grab their attention, but is basically harmless.
If anyone needs help. Holla atcha boy.
If you’re comfortable, give us a link and we can take a look see.
So I’ve been talking to this girl that messaged me for over a week now and she’s sent me 6 multi paragraphed messages. I assume that’s a good sign, but I’m pretty gun shy at this point. Not sure how to move to the next step.
