Drawing a travel map for a blog

I travel a lot and would like to start showing a map on my blog of where I’ve been this month. What I envision would be the ability to draw a line between Town 1 to Town 2 to Town 3 to Town 4. I want a straight line, not the road route.

Can anyone point me to such an online mapping function?

Like this?

Gmaps Pedometer

Perfect, thanks. I couldn’t quite remember that use of Gmaps but I knew the wisdom of the Dope would be there for me. I’m going to lose some time on this - it will be fun to do not just month to month, but going back and tracking travel/visits across an entire year.
