I am fixin to build one like the avery migrator but with a few modifications. First I am going to make on a sled like the ones in cabelas but big enough for me to lay in. It won't be collapsable but that just means less time to set it up. It will still have the two doors with bungee cords for assisted opening, but will also have a another door that opens by my feet so i can get in and out easy. Also when all the doors are open it will be an ideal place for decoy bags, gun, and coffee. Then I'll just drag it into the field and shoot at whatever geese decide to come in for a closer look.(HA HA)
