Cheap summer fun

There’s not a lot of sunshine out there, but summer is still on my mind. I’m trying to come up with some family day trips/activities without having to drive too far or spending too much money.

Here are some ideas so far: Hiking in Riverside State Park, Tubbs Hill in Coeur d’Alene or the bluff on the South Hill; spending a morning at the public library; going to the pools, any of the lakes or to the fountain at Riverfront Park; learning about plants at Gaiser Conservatory in Manito Park; picking fruit at Greenbluff; watching a movie at the Garland Theatre for $3.50 a ticket; Mobius…

Any other ideas to prevent the “Mom, I’m bored” complaints? The criteria is simple: local and cheap. Free would be great, but anything at $6 per person or less would be fine, too. Thanks for your input!
