I am 81 and own two motorcycles. When I can not ride them and feel unsafe on them, then I will wait another five years and take a look at my motorhome driving ability and safety. Rode one scoot 200 miles yesterday in the rain and had a ball.
One of my problems, however, is that Texas raised the speed limit on IH10W west of Kerrville from 75 to 80mph. Ya gotta keep an eye out for those red necks. lol
