For me, the most enjoyable forms of conveyance are ones without motors.
-I'd much rather paddle a kayak than ride in a powerboat. Even with all the lakes around me, I have never ridden a waverunner, believe it or not. When I lived on the lake I'd come home from work and paddle the mile across to the other side. On the way back I'd stop in the middle and just sit and watch the sun dance on the waves. It is very meditative. Being so close to the water is a cool sensation.
-I'd much rather ski than ride a snowmobile. On the ski patrol, I'm required to do both. Snowmobiles are loud. They ruin the serenity of a quiet, snowy day.
-I'd much rather ride a bike than a motorcycle. Again, they're loud and there's no sense of accomplishment when you get to the top of a big hill.
-Although I haven't tried it yet, hang-gliding looks like something I would really enjoy.
Of course, this is just my opinion. If you had the choice, what form of conveyance would you choose?
