Camp Good Days is getting ready to celebrate its 40th birthday building a museum to share the camp's history.

Founder Gary Mervis created the camp after his daughter's cancer diagnosis in 1979.

It allows sick kids to have the camp experience, free of charge. 

"We couldn't do what we do if it wasn't for so many people and like I said in big ways and small ways," Mervis said. "I mean this summer we'll have over 200 volunteers. These people are giving up a week of their vacation time, time away from their families, in order to come out and provide some good days and special times for our children."

Mervis hopes to open the museum before the season begins, just after the Fourth of July.
