We used The Thing (see separate thread) as support vehicle for a unicycle trip around White Rock Lake. Took two 20" unicycles, drinks, bike tool kit, pumps, and off we went- taking turns unicycling and riding the trike. Worked pretty good. Got smoked by lots and lots of roadies, though. Saw 3 or 4 recumbents, including one hand bike, two different tandems.
