Yep, there are a few flyers at my field that we basically give a wide berth to. They go up with their pocket rockets and aimlessly wander all over the aerodrome, to include flying against the pattern! Nothing more unnerving than knowing that there's someone's plane cruising towards yours head-on at blinding speeds![X(]
When I first learned to fly, I found landings to be the easiest part! To this day, landings are actually the less stressful part of my flights. I had a excellent instructor that talked me through every stick movement of every manuever. Landings just seemed to come easy, but the rest of the flight, that's a different story!
When the "wanderers" are up in the sky, I'll just park my plane until they come down...
