I got some aluminum signs when I first bought my farm about 10 years ago and replaced all the signs with those. For the life of me I don’t recall where I got them. Amazon? Menards? Can’t remember. I also put up some plastic signs because I ran out of the aluminum ones.
Bottom line is the plastic signs have lasted just as long. The aluminum signs are all there, but the paint faded so bad they aren’t that readable anymore. The plastic signs look good still.
The big thing that I think I accidentally did right was that I glued the plastic signs on to treated plywood backing with some construction adhesive. Then I screwed them up with stainless screws. If you just staple the signs on the backer board, the staples rust within a year or two and the signs fall off. And if you use regular screws in green treated wood, the chemical in the wood eats the screw.
BTW, I talk to hundreds of hunting property owners every year in 5 states across the north/midwest. According to customer reports, Wisconsin is second only to Illinois as far as trespassing and theft complaints I hear about. Theft seems to be a HUGE issue in Wisconsin, lots and lots of theft of cams, stands, equipment, electric fence modules, etc. Seems like certain areas of WI, the local dirtbags know where all the leases and non-resident owners are and they know these are easy target properties for poaching, theft, etc.
I say this only to tell guys don’t get complacent thinking that just because nothing has happened on your property, that nothing can ever happen. Use hidden security cams, lock gates, chain up stands, etc, etc.
