Let's go bowling!

Bowlerama in New Castle has inexpensive bowling on weekdays. It's $3.50 per game for seniors plus $5.50 for show rental.
You can't reserve lanes, but it should be no problem since they have lots of lanes and are not very busy. The lanes are in good shape--I checked it out.

I suggest 3 people per lane, but we can adjust that as desired.
Two games would likely take around 2 hours with 3 people per lane, but we can adjust number of games as desired.
We can meet at the bowling alley and pay individually. They will give as adjacent lanes--the number of lanes has no effect on the cost.

They sell food, but I don't know what it's like.
