Flying with a bike on Southwest. Or maybe a bike shop in Detriot?
 

I was thinking of going to Detriot to do some urban exploration. Have any of you flown with a bike on southwest? how much do I have to rip my bike apart?

My other option is to buy a bike when I get to Detriot. Any ideas where I can pick up a cheap/ridable bike from Detriot?

The Hub is the place to go to buy a cheap ridable bike. Their web site is http://www.thehubofdetroit.org/

You can also get daily rentals and a more modern bike at the Wheelhouse Detroit bike shop. http://www.wheelhousedetroit.com

Myself or one of the many other local cyclists would likely be able to give you a tour while you're in town. You might also consider coming to town during our Tour de Troit ride on September 19th. There's more information at http://www.tour-de-troit.org Last year we had 1,100 cyclists riding through Detroit. It's a big event with great food and beer at the end.
