DIRTy job

My company has a volunteer month in June where the company pays for employees to take a half-day and volunteer in their local communities. I oversee this program globally, and am very involved in the planning for the Dallas office. We try to hit all the "hot-button" issues - kids, animals, the environment, vets, the elderly, the homeless, etc. One of our events is taking place at a VA hospital, and they want us to paint outdoor furniture and help with some landscaping. No biggie, right? Wrong. They have asked us to bring 4 yards of top soil. Which equals about 75 bags. Um, what? As if I have the arm strength or the trunk space for that kind of haul. Wondering if we're getting a little taken advantage of here - we'll only be there for three hours! I think the outdoor furniture painting is plenty. Sheesh.
