I plan to hunt a waterfowl refuge for deer this Fall. I will have to carry my stand in and my deer out. I realize I can buy a good one for about $100, but I like to build my own. I am thinking a single front wheel, since the trails are narrow. I have access to some aluminum extrusion, but can`t weld alum. If I use electrical EMT, that I can weld, and still keep pretty light. Have some ideas, looking for some more? Thank, hc18flyer
