Been watching too much bow fishing lately and started to think " hey that would be cool" . Get to your tree and shoot one of those arrows about the height your stand is going to be and lock the reel, when you get up to the arrow then you could just drag your bow up. Then it would be simple to retrive your pack just shoot that arrow through it and reel it to your stand.

On second thought it might be kinda tough on your pack after a while.

My bows are a tool i dont abuse them but they are used, and if i never got any wear on them i wouldnt have an excuse to buy a new one every now and then.
