I like riding my bike. It is smooth, comfortable, capable, not much more difficult into a 25 mph headwind as on a calm day. Hasn't thrown me on my chin in 4 1/2 years, as the MTB's and cruisers did many times. Great visibility, easy on and off. Carries enough tools & supplies to get me home without help most of the time. Supports up to 5 day excursions to my summer camp in the woods. From it I've seen cows, horses, sheep, goats, llamas, rabbits, squirrels, groundhogs, raccoons, weasels, coyotes, deer, chipmunks, hawks, crows, eagles, bluebirds, prairie chickens, ducks, geese, woodpeckers.
I used to enjoy hiking, but US Army knees by age 62 put the end to that sport.
