I used this program last year. It was great. Sign up the kids and they bowl
2 strings for free. You pay for shoes ,that's it. Bowling Alleys all over
the country participate. There is a one time fee if you want to sign up a
bunch of adults too.
Great summer time activity, especially when it is really hot out. My niece
loved it. Brought different friends every week.
