Okay before you laugh hear me out.
I think a petting zoo would be a great business. Buy some goats and pigs and then have a little farmers market out front with overpriced jelly and pies. I visited a few over by me (new york) in the last few months and it seems fool proof. I also stopped at one in massachusets while i was there for a wedding about 2 weeks ago. The petting zoo part was free! The little store they had was super busy. The place even had a friggin alpaca walking around.
I plan on buying a chunk of land in delaware and starting this up. My worry is if its legal to do this on residentially zoned land. And the insurance has to be crazy. If anybody is familiar with rehoboth beach in delaware, not far from ocean city in maryland, then you know these areas are blowing up and it seems almost impossible to have a failing business there.
