I'm late on this post....any update?
I not only adopted Jack from there, but volunteered there for several years. My advice is...be ready to work hard.
It's hard work but VERY rewarding. Also, the best thing that can happen to a rescue is a volunteer they can depend on. So no matter what you say you can do, if you can be there once a week, twice a month, whatever it is, be sure to follow thru with what you have committed to or at least give notice if you can't. I think many times the volunteering thing, people may feel since they are giving their time for free they can be more laid back about it, but really, rescues are in such desperate need of help, that if you are someone that follows thru, you are golden to them.
So that means, don't make promises you can't keep because they will need whatever you can give time and effort wise. Be sure to know exactly what you really can do and commit to that. Ironically, though I like to be creative, what I really all I really could commit to for them was just clean cages. Doesn't sound glamourous, but I found it cathartic, and that work is very important to rescues. I want nothing to do with the computer or creativity when I volunteer, as I am mentally maxed out with that kind of work for my own site, so I just don't mind cleaning up poop. (You can pet all the bunnies that way though too--- what's better than petting a gobzillian bunnies in one day!). Plus, there is something wonderful leaving a shelter/rescue spotless when you leave. Very satisfying.
Good Luck and I hope it worked or will work out.
I haven't volunteered there though in many years because I moved from San Francisco to the East Bay, and trying to get through I-80, then across the San Rafael bridge became too time consuming as BinkyBunny grew. I do miss working there though. A vivacious passionate fun group that is highly motivated so you will never be bored... you will learn ALOT!
