I have way too much free time on my hands. I visited the USA map and the World map of doper locations and calculated the number of towns and cities there that I have actually visited. There were 38 towns and cities I have visited. I counted a place only if I’ve been within the city or town limits. In some cases, it was hard to tell if I met that qualification. For example, I guessed that I was inside Hudson WI when I passed through on I-94 and I guessed that I wasn’t inside Atlanta when I was at the airport there.[list=1][li]Los Angeles, ca[/li][li]San Diego, CA[/li][li]Challis, ID[/li][li]Laramie, WY[/li][li]Sioux Falls, SD[/li][li]St. Cloud, MN[/li][li]St. Paul, MN[/li][li]Minneapolis, MN[/li][li]Hudson, WI[/li][li]Ashland, WI[/li][li]Milwaukee, WI[/li][li]Marquette, MI[/li][li]Flint, MI[/li][li]Ann Arbor, MI[/li][li]Davenport, IA[/li][li]Chicago, IL[/li][li]Indianapolis, IN[/li][li]Columbus, OH[/li][li]Lakeland, FL[/li][li]Tampa, FL[/li][li]Coral Springs, FL[/li][li]Rockville, MD[/li][li]Baltimore, MD[/li][li]Columbia, MD[/li][li]Philadelphia, PA[/li][li]Mechanicsburg, PA[/li][li]Canandaigua, NY[/li][li]Albany, NY[/li][li]Saratoga Springs, NY[/li][li]New Brunswick, NJ[/li][li]New York, NY[/li][li]Providence, RI[/li][li]Fall river, MA[/li][li]Wellesley, MA[/li][li]Boston, MA[/li][li]Sanford, ME (of course)[/li][li]Toronto, ON[/li][li]Niagara Falls, ON[/li][/list=1]
I believe the Atlanta airport is, in fact, within the city limits. It is certainly considered part of metro Atlanta, so you can easily say you’ve been here. 
I have been to:
- Boston, MA
- Wellesley, MA
- Providence, RI
- Albany, NY
- New York City, NY
- Pittsburgh, PA
- Columbia, MD
- Baltimore, MD
- Laurel, MD
10)Washington, DC
11)Johnson City, TN
12)Columbia, SC
13)Anderson, SC
14)Augusta, GA
15)Atlanta, GA
16)Jacksonville, FL
17)Tampa, FL
18)Miami, FL
19)Nashville, TN
20)Jackson, MS
21)Baton Rouge, LA
22)Louisville, KY
23)Cincinnati, OH
24)Columbus, OH
25)Cleveland, OH
26)Kettering, OH
27)Indianapolis, IN
I’d have thought there were more. As you can see, my travels have been primarily in the Eastern half of the country. I didn’t pull up the foreign map yet, because my connection is running slow. sigh
And, I believe I’ve driven through Sanford, but I can’t say for sure, so I didn’t include it in my listing. I did do a lot of traveling around Maine during my college years.
I’ve got a very short list here…
- Honolulu, Hawaii (Although I know I’m not the only Hawaii doper, I’ve still got the whole state to myself! :D)
- Las Vegas, Nevada
- Los Angeles, California
Let’s see…

I think that’s it.
28, I think.
US: Baltimore, MD; Laurel, MD; Boston; NYC; Providence, RI; Fall River, MA; Chapel Hill (duh), Raleigh, Durham, and Cary, NC; San Francisco; Virginia Beach and Norfolk, VA; Chicago; Rehoboth Beach, DE; Rockville, MD; Vienna, VA; Washington, DC; Richmond, VA; Harrisburg, PA; Sanibel and Tampa, FL.
International: Dublin, Glasgow, London, Manchester, Salzburg, Belfast.
Are we counting by smileys, or by the actual town listed? I counted by the latter, because
[ul]
- some of the towns grouped together are really quite different places, eg North Hollywood and Pasadena
- some of the towns grouped together are really nowhere near each other (Manchester is not in the “Leicestershire area”)
- it makes my list longer

[/ul]
Anyway, I come up with:
- Dublin
- Belfast
- Glasgow
- Leicestershire
- Manchester
- London
- Toronto
- Montreal
- Sacramento
- San Francisco
- San Leandro
- Oakland
- Concord
- Berkeley
- San Jose
- Santa Cruz
- LA
- Pasadena
- North Hollywood
- San Diego
- Las Vegas
- Salt Lake City
- Albuquerque
- Omaha
- Cleveland
- Atlanta
- Richmond
- Rockville
- Washington
- Harrisburg
- Pittsburg
- Rehoboth Beach
- Columbia
- Baltimore
- Laurel
- Philadelphia
- New Brunswick, NJ
- NYC
- Albany
- Saratoga Springs
- Providence
- Boston
plus the following airports I’ve been through which I don’t know if they count or not:
- Amsterdam
- Phoenix
- Minneapolis
- Chicago
- Miami
- Dallas-FW
I should mention also as a small child I made a couple cross-US trips in a car with my parents, so there could be more that I don’t remember.
