I think a year's membership at a golf course is much more useable and he might get alittle exercise. :)
I first got dragged kicking and screaming into kayaking after arriving here in Memphis in 1997. Aside from the sport of running the Mississippi at flood or surfing in the wake of barge river traffic, there are plenty of Mississippi tributaries to explore.
In general, I rate kayaking just behind motorbikes and just ahead of parachutes. A lot depends on locale and convenient local waterways, of course, and it's helpful to either own a pickup or have a real tolerant friend who does.
