My fiance and I are starting to look at wedding venue's around NJ. I've been scoping them out on here for a while though

This is the first time I'm posting something so I'm sorry if this was already asked!
We wanted to look at less traditional sites for a reception but I don't seem to be finding a place like that on here... Maybe an old mansion of some sort? We haven't firmed up a date yet but we were thinking very early summer or late September. Does anyone have any ideas? We live in Central Jersey but we are pretty flexable!
Thanks!!!
