I have been thinking about getting an inflatable kayak that I could backpack up to this beautiful mountain lake:

I came across this thing called Intex Challenger K1:

I have seen it as low as $55 on Amazon. I figure if I only use it once it is still cheaper than taking my wife out to dinner. (I thought about a float tube, but that pond is icy, so I would need to haul waders or a wetsuit in addition to fins...of course I could put all that stuff in my brother's pack...)
