I have a string looped though the front tie down loops and just tie it to the frame when I use it.
I stood up on a long trip before I started to tie it off. Flew off and a flip'n semi ran it over. Lucky me, it just broke the valve. AirHalk sent me a new one (valve) and I've been good ever since.
Thanks to the Interstate Highway System, it is now possible to travel from coast to coast without seeing anything.

I never plan a ride, just the destination and that's always subject to change.
