My brother-in-law used to do this, collect roadkill and disperse it. For no charge. He and a half dozen others would carve the moose into useable portions and disperse it to needy families. For no charge. My brother-in-law used a tow truck. He would get the call, get to the moose, run his cable to it, drag it in, hang it, tie its legs down so it did not flop and be gone. 

The moose guys, saw how it was done, had the state buy them a fleet of tow trucks so they could copy it, and now use the same technique. My brother-in-law has not had a moose call since. Once again, government being the only solution to a problem, have stepped in and saved us from ...um.............somethiong.............I guess!
