I'm very new to flying, only had two training sessions so far. That said, we have four benches at our field and are full most of the time. I am on crutches and couldn't work on the ground if I wanted to. I move a chair out to the pilot area as I'm limited to how long I can stand on a bad knee. Club members are great and help me enjoy the sport a lot. My point is, some of us folks can't work on the ground and need the benches. I learned a few years ago (the hard way) on a friends plane to get behind a running engine to remove glow-driver and make adjustments. Accidents do occur and we need to use our heads and learn from them. I'm done ranting now.
