I am only minimally involved so far, but I value the preservation of open land for recreational use. I also like working with my hands and working the land - not something I get the chance to do at work at all!
I also love to wheel. Working to wheel is a fair trade in my mind.
I hate the political action end of things and will never volunteer for that. However, I am willing to do management tasks if needed but that is indeed a chore
I think it is a rare thing - I think they call it Egalitariansim - for people to be willing to work for an ideal. Most people are pay-to-play level IMO. This may be something to consider in the future to bring in another layer of 'volunteers'. If people had to volunteer at least one day a year to participate in Fall Crawl, for example, we'd have a lot more volunteers I think!
