I need instruction, or at least advice, on beach landings. What's the best way to tell if it's too soft from the air and any other gotcha's. I'll be flying a C-172 "Superhawk" with 8.5 X 6 tires all the way around. Was thinking of Montague, the Tsiu, Silver Salmon Creek to start. Although admittedly I've never been to any of them.
