Dump OK, Water not recommended

We stayed at a dispersed camping spot near this gas station and asked the clerk if they had a spigot for fresh water. She sent us to the spigot right next to the dump station. The dump station is good and easy to get in to even with a large rig, but there's no way I'd ever fill my fresh water from a spigot next to a dump station. Clerk suggested we could fill up some jerry cans at the local Walmart, as they have a filtered water dispenser in the back of the store. That's what we did and it worked out fine. Just took a few extra trips, but I'd rather pay for clean fresh water than get free contaminated water. So use the spigot at your own risk, but not for us!
