Free: Contests & Raffles.
im not hating on the site, but i have been on others that at least will get more comments that 2 or 3 with 60 or so people having viewed.
dont try to "bribe" the land owner, he might take it as being a sucker. you can offer to do some labor, or post trespassing signs on the property, but every year we hunt deer at our place we give the landowners a gift, something like a gift certificate to a restaurant
