Years ago we made our game carts..First was a single wheeled with bicycle brakes with handles on both ends..It worked alright in fairly flat ground but was tippy..Next was a dual wheel as the ones they sell now and without breaks...It also wasn't very good in steep terrain and the lack of breaks can be dangerous.

I now use a Lewis Chain Saw Winch and alot of rope and cable.I suppose in flat terrain or old logging roads game carts would work pretty good but around here the use would be very limited.
