I'm sort of surprised
I though I was the only loner out there but the lack of response from your area indicates there are more like me. A couple of years ago (well 3 actually) I flew from Southern California to Fargo, ND for a race that was scheduled at the same time as Oshkosh (I know - who was the scheduling genius) and I heard many groups on 122.75 when I was going in to refuel at Provo, UT. If you monitor that frequency you may end up with the next best thing to flying in an organized group. Good luck - see you at the big show.
