Try making some ground blinds with the materials you can find in the woods. Such as fallen trees, limbs, long grasses, and even leaf piles that you can rake up in front. Look around this summer for discarded 2x4's or plywood (unpainted) that you can cut and fashion for a backing for these blinds. I hunt a public area of over 30 sq. miles with little hunting pressure and I've built many blinds over the years with my only cost being my time, sweat and hard work. Hunting costs over the years have gone through the roof and I can appreciate what you are saying about costs. If you will be using variable locations (due to wind, travel corridors, time of year etc.) then building your own blinds would be most economical. You don't need much, just a little cover so that you can comfortable sit in a chair. Pre-plan and scout your locations now and then spend a couple of days in the woods constructing your blinds. I've harvested numerous deer over the years sitting behind such blinds and if constructed with care other hunters won't even see them when they walk by. Best of luck with your projects if you decide to build them.
