Kind of depends what you want to do. Want to be like the frontier's men of past, exploring the nook and crannies of the local river, go for a canoe. Want to join the local brigade and drive around with a kayak that never see any water but looks cool sitting on top of your VX or what ever, then get a kayak. Want something that give you a real workout, something you can do indoors in the winter with a ergometer. Something that will give you a real workout that is non impact, then try a rowing shell, either scull or sweep. But I guess you can tell by my user name where my Sentiment lies.
Greetings, Earthling. We come in peace... Never mind "Paris to Dakar", the VehiCROSS looks ready for the Martian desert.
