Last year I did a thread on the clip shot camera mount that 3R sells. I love that thing but during a spring backpack trip I broke my camera. I will probably have to wait til Christmas or longer to replace it so this year I'm stuck with my phone.
I'm sure someone has already thought of this but here is what I came up with for a mount. Nite-ize gear ties work great. I'm sure there are many other hunting uses for these things as well. I got a 2 pack of the 18" models. I think they were less than 5 bucks.
