I am getting tired of spending (wasting?) time checking out areas that should never have even been mentioned as possibilities. I think a dose of reality is needed.
"parking situation ... only room for about 60 cars"
Had to laugh at this; I suppose it illustrates that there's an orders-of-magnitude difference between DVOA and UNO. We had not quite 40 for the last meet I organized; guessing they came in maybe 20 cars.
(excuse the very belated comment)
Steve the problem with the 60 car capacity is that the park gets very heavy use from other users (day hikers, etc.). On a nice weekend, they will fill up the lot leaving little to no excess capacity for a O event. A 60 car lot would be on the small side for a DVOA event with all courses even if 100% of the spaces were allocated to orienteers.
