I would not waste a dime on a Ameristep blind if it still has exposed zippers in the northern climate.
Also if we stake down our blinds in Michigan many times the ground freezes during fire arm season and you can't pull the stakes.
My favorite potabale is this one with PCV frame corse covered zipper for the entrance and roll up windows or tie them closed.
I have had as much as 20 inches of snow on it too.
I normaly don't tie the cover to the fram if set where the wind can hit it as it will shake the PCV joints apart.
