Thanks Wizard, I may just bring one small wire brush to see how it goes. Also if I can find a small pail I might try to locate some clay type mud near the springs and smear that over some of the graffiti to at least cover it over until the next rain storm. Not sure how hot it is going to be on Friday, I will be there from around 8am to about 3pm, probably not the best time of the day to be working on this graffiti project. I am also expecting to find a ton of trash at the springs after this Fourth of July holiday, picking that up and hauling it out may end up being my main project for the day.
