How much dose it coast for musum

Museum is free.

Free

I try to donate between 2-6$ for every park or nature preserve I visit. Helps to keep them nice for future people to visit

Yes, free but it is good to donate, c as use it helps

Suggested donation $2 for adult. I don't like the limited open hours, only noon to 4 pm even during summer. Only open at weekends after summer. It's a waste of effort to keep it well.
