RE: Summit Climber
Terry,
Enjoy your new stand, it's a beautiful thing. As far as your day pack, I just clip mine on with a "D" ring where the back straps are strapped to the stand.
I also just picked a a bag that fastens to the front bar of the seat part at Dick"s for like $10. I plan to bring just a few items up the tree in the bag and leave the pack on the ground.
Many other scenarios, I'm sure you'll work it out.
