We played to play campus-wide capture the flag at the camp I went to as a kid a couple times and I will never forget the experience. The camp spanned an enormous area with all kinds of varied terrain and we had ~170 campers and counsellors playing. I vividly remember patrolling in an out-of-the-way part of our area by myself amongst the rhododendrons and detecting some movement; a counsellor from the other team was hiding amongst leaves. A frenzy chase ensued.
One twist to this game on the enormous area was that neither team knew where either flag was, so you had to send groups to scout your own side to figure out where your flag was. I get why the person who posted this article chose not to have jail, but the jail was another fun dynamic. It gave the opportunity to break people out of jail, which was another goal besides the flag.
The author is completely correct that these are lifelong memories.
