Being 8 miles from the Thruway may be a bit far for a lot of folks just looking to park overnight. W&E would help especially for those that want to run their AC overnight. But a lot of folks tend to look for a WalMart or a Cracker Barrel right off the interstate for convenience, and it's free.
Your Dairy farm and brewery however would be a possible destination based on someone not wanting to have to travel too far from the metro areas and who would like the quiet farm atmosphere. If the sites will have a little shade, maybe a small brook, and a view of the dairy herd, a lot of people would find that very relaxing, and if the brewery did a friday or saturday evening tasting and tour maybe even mixed with some other local products (wine and cheese maybe) I could see it becoming a nice niche location.
