I found this website today, its goal is to link up people that have space available for gardening that need help, can't tend their gardens any longer, or just have open space they want to be utilized, with those who are seeking a place to garden. I thought this may be a great resource for folks in both parties, those with land and those wanting land.
It's easy enough to use, you can just enter a city name and state rather than an exact address and do not have to use your full name either. You can call yourself whatever you want for a name, just need an email. I hope this helps someone!
