If you have to drain the system, land and drain the system. I flew from Dallas to Oshkosh, I could have made the trip with only 2 stops. However due to back problems, I sopped 3 times before arriving at my home airport. Twice to drain the system and once to walk around. I'm in the 60+ group and we need to understand we are no longer in our 30s. On the way to and from Oshkosh, I found a tree.
