Why volunteer? Maybe you are 'suddenly retired' or your job search is dragging.
When you volunteer your time to help someone else, you can regain that all-important sense of accomplishment. Volunteering also gets you out with other people rather than buried in classified advertising and job boards.
Since you want to enjoy your volunteer time, why not choose your volunteer organization as you would choose your ideal employer. Some of the questions in another of our resources, Qs_Your_Ideal_Employer , may be helpful.
How did I find these links? I started in the northern part of our area and Googled some of the cities working my way south. (e.g.: Fort Collins CO volunteer)
