We often check prices for things on Amazon.com since they're frequently less expensive. Hard shell kayaks ran from the mid-$200 range up to truly staggering amounts. It was on Amazon that we came across inflatable kayaks. Prices for kayaks with paddles, pumps, and carry bags started at under $100.
We decided to buy the Challenger K1 and the Intex Explorer K2 Kayak. The K2 (which is a bit more expensive) is for one or two people; our thinking was that we could take a dog with us, or we could actually go out together if we wanted. Reviews were pretty decent for both of these items, but there were several mentions of trouble with the skeg, the small fin at the bottom rear of the kayak that helps keep the boat tracking on a straight line.
So, deciding that these products were affordable enough to take the chance on, we placed our order. Of course, then we needed various waterproof items for things like cameras, keys, wallets, plus water bottles and other stuff.
Then we waited for the UPS truck.
