Visit the carnival
Go to the drive in ( this is my faverite) its cheap and entertainment for the whole night not just an hr
My Dh and I go early and put our futon mattress in the back of my MILs truck. its cozy and romantic.
Find a local Drive in https://driveintheater.com/index.htm
Check your local area for ideas Usually your city will have an booklet of things to do in your area.
i found all kinds of things I never knew happend in our area a lot of them are free or just have a gate fee
and You can walk around all day.
Examples being: a local park collects surup from the maple trees. they have a pancake breakfast and
people showing everything from how the natives used to collect and use surup to how they do it now and how to make kettle korn
I really enjoyed my self and ive never had better kettle korn. breakfast was $5 and everything else was free.
