What system should I get to pick up a weak, free wifi signal at camp grounds that is strong only at the camp store and not at my camp site that can be several 1000 feet away?
You can get WIFI-Link Warrior +Omni 8 dbi+ cable Kits so you can receive the signals from all the directions within 2000FT range.
The only difference among kits is the length of the cable you need.
