We spend a lot of time outdoors. We live in WI and take advantage of all the state parks in our area. For $26 a year we can take numerous hiking trips, learn about nature, and see awesome waterfalls and other cool things. In the winter we go to those same parks for CC-skiing.
There are a lot of neat low-priced and free things sponsored by different levels of government. My tax dollars are supporting them so I take advantage of that!
