Wind would be your biggest challenge to that idea...
Well yeah, that and getting shot!...Imagine somebody seeing a damned old ice tent wandering aimlessly down the beach in the broad daylight? In the Upper Peninsula? With an eerie blue glow from a blacklight emitting from the bottom? Like its gotta be a possessed portashidder or some sort of alien 'ground kite' or something?
I know what I would think! ..."WTH is an ice spearing house doing wandering around out here on the beach in the broad daylight?" Does it have rabies? Is it demonized? I'd open up on it in self defense! BOOM! All sorts of drawbacks, but I DID consider the concept! I bet it would work though..Like you said, if the wind was light....
I should probably patent a 'daytime Yooperlite folding hunting tent'...probably could sell the hell out of them to next seasons tourists! ...nobody likes to be out in the dark up there!...the bugs are horrible!
