I have lived in the Mount Diablo area for several years, and it took me a while to learn that Save Mount Diablo even existed, let alone was needed. As it turns out, about half of the mountain ecosystem is still unprotected. I'd hate to see a massive development next to the park, or find a trail that ends at a private fence. Worse still would witness the side of a mountain scraped off for mining, or a pristine meadow used for inappropriate purposes like a landfill (this almost happened! search for round valley near marsh creek). I don't have time to volunteer, but I do enjoy the views of the mountain and occasional hike on Diablo and or drive to the Summit. I want to keep it that way, so I donate every year to this non profit. I have the utmost confidence that they make the best use of my money. They publish an annual report, so I can see that over 90 cents of each dollar goes to buying land. I learn which land was acquired, how it is being restored, and why it is important. There are special invite only hikes to explore new park land. Also, Save Mount Diablo doesn't waste paper, my time, or their time, by sending me a bunch of unnecessary mailings, begging for more money. They keep me connected without being inundated. I feel good knowing my money is helping save something that we can all enjoy. I hope you consider donating as well.
