Filling up at gas station

I know how you feel about being nervous filling up when you're new at this. We too were in that situation. We would first plan a stop when we were at half a tank to allow for time to find a spot to get in and out easily. When DH was filling, I would set out by foot and scout out the exit if it wasn't easily seen. Sometimes we would have to back up and I'd get out with the walkie talkie just to spot check any obstacle. Don't let others rush you! Take your time. We've had to resort to tight gas stations when low on fuel, and back all the way out, but DH didn't care and I would watch for cars for him. If you know your route, you can use google maps to scout out the fuel stops ahead of time. I know it sounds a little over OCD, but if that's what it takes for a little peace of mind when you're new then do it.
