Yeah I frequently ride with a trailer, every two weeks or less I bring my young daughter to my place in one - it's a crappy Little Tikes one I got from Toys R Us.

Last Thursday I used it with my fixed gear - quite a lot different I'll tell you what, but not bad - was just careful (special cargo is worth the extra time/effort ).

I usually break out the MTB for trailer runs though, it fits that bike way better and it's just more sturdy. I'm probably going to get rid of it soon as the sprogg is getting too big, trail-a-bike time and maybe a BOB trailer for actual cargo is in order.
