I'm not an airline pilot and can't even call myself "experienced" at going
into OSH, but I have flown there more than a dozen times in the last 20
years, mostly on Friday and Saturday.  I think it would be fair to say I
haven't had any problems BECAUSE I have concerns.  To say one has no
concerns is to ignore the reality, IMHO.  I find it almost necessary to have
2 pilots on board, or at least a passenger experienced in spotting potential
traffic conflicts.
