I was Course Setter for the WPFG 2001 in Indiana. That was the 2nd time orienteering had been included, and as far as I know it has been in every games since then. I think this is the first time since 2001 that the Games have been back to the States, so maybe another 10 years?
In 2001, they were very strict that there would be no public runners allowed on the courses; only eligible police and fire personnel. All volunteers were vetted and given identification, access was supposed to be pretty tightly controlled. So I am really happy to see that this seems to be relaxed for this year, although perhaps the added security of being on the USMA grounds was a factor in that decision.

Interesting note. Part of the task of organizing was having a "terrorism plan". There was great concern about security for the large gathering of police and fire personnel, in part because Oklahoma City bomber Timothy McVeigh was scheduled to be executed (and in fact was) at a federal prison elsewhere in Indiana on that same day.
