I have over 4,200 hours of volunteer service to the US Fish & Wildlife Service, as a photographer and heavy equipment operator restoring habitat. I have donated many hundreds of slides and prints to the Service to use in educational programs. There are always individuals in about any organization that will push you for all they can get. Stand firm as to what you will and won't do. After all, if you're giving away your expertise, you should have a say in the matter. It's always a good idea to get an agreement in writing. All in all, I have enjoyed my volunteer service. I have had to deal with a few idiots, but the good far outweighs the bad. Also, I have received many certificates and letters of appreciation and the President's Award for volunteer service. That makes me feel good. These and hundreds of project record photos give me something to look back on in my retirement and say
"yeah, I did all those things, and I'm proud of it."
