Volunteering on outdoor projects for different organizations such as the US Forest Service, Indian Peaks Working Group, BLM, etc, are great ways to enjoy the outdoors, plus return something to the health of the environment. Volunteers for Outdoor Colorado is a great organization that connects volunteers with projects sponsered by different organizations, including the VOC itself. Projects include trail repair crew, wildlife surveys, user impact surveys, and many other diverse projects. Contact them for more info on other Eastern US AMC clubs.
Fishing can restore a sense of sanity.
If one ever had it. I learned how to fish on a small Pennsylvania trout stream. I'm getting the hang of fly fishing, the only way to go in most of Colorado. I also fish around my parent's house in Florida. Found her in my house, and didn't have the heart to kill her.
