Have had:
1980 Yamaha MX 100
DR200
1973 Honda CL 200
Honda Rebel 250 (didn't really ride this more than a few times - too small)
1993 Kawasaki ZX 750
Sold the last one after moving to SE Florida. The roads are straight, the scenery is nil, and the drivers will kill ya.
WIth the gas prices the way they are, a bike sounds nice, but I drive a full sized pick-up for a reason, and I'm willing to bet I'd severely regret being in or on anything smaller at some intersection. SE Florida might as well be the final scenes of Mad Max: The Road Warrior. The constant highway fatalities are reported with nary a blink of the eye.
