Vacant Land Property Insurance

[Joe L.]

Hello all - I am part of a non-profit organization that owns vacant land in the state of PA. Does anyone have any recommendations on insurance companies who can underwrite something like this? I called the major providers (ie GEICOs, State Farm, etc.), but unfortunately they either only underwrite homeowners or the land needs to have a physical dwelling. I tried Googling for some companies, but I'm not sure I can trust some of the initial search results. 

Any help will be greatly appreciated!
