Edible????

LOL....Why is that important? If it's freezing rain.....you're gonna have ice forming on EVERYTHING. Cams. Cables (check that slide!). nock. Fletchings.

You name it. It's gonna get ice on it. Why not just get a tree umbrella, lube your BH and check it (visual) occasionally. Problems solved for $25 (umbrella) and $.02 worth of WD40.

Shoot a slammer.
