looks good, but in many public places I would be making it so it could be locked to a tree, as folks here have too many sticky fingers, if you ever left it away from where your hunting(or over night so not to have to bring back in next day),
on a side note for anything looking to duplicate this, good HD plastic slides for the bottom would be Snowmobile hyfax's, even used one,s will last a LONG time, and if you have any snowmobile shops near by, odds are they will have used ones they are planning to throw away, so can maybe get them free!
they also sell, HD Teflon embedded one's, that should last a forever, but there not cheap, but for being dragged far behind a atv or on hard pack pavement often, they would maybe be worth it!
just a extra tip!
