The amount of free activities may largely depend on where you live. In my area, we have things like Montford Park Players who perform takes on Shakespeare plays every weekend at an outside theater, admission is free or whatever you want to donate. There are concerts and other activities every Friday night in a park downtown. Library for movies and books, but they also have book clubs, story hours for kids. We have alot of trails in this area for hiking and bike riding. Ball parks if you can get some people together to play. There are waterfalls and lots of picnic areas. While gas is expensive, I am fortunate enough to live an area where most of these things are available within a 10 mile radius. We also had game night every Friday when our children were home. Lots of board games with a special inexpensive homemade treat that the kids often helped to prepare. We go fishing at local ponds/lakes. Internet has tons of ideas for crafts, gardening and other projects. We have a free newspaper that comes out each week available at most convenience stores that outlines all the things to do in the area, both paid and free. Check with your local better business bureau, colleges, parks & rec dept, privately owned business (especially those that are in the arts, such as pottery) - many offer free or very low cost classes.
