I am placing my first D5/T3.5 cache. It started as an attempt to help an older cacher who completed their Fizzy Grid, did not record or save the finds, and then noticed that 5/3.5 went "Open" after he knew he has logged one.
My initial thought is DONT CHANGE THE D/T RATING! AFTER YOUR CACHE IS FOUND.
Your thoughts as to why you would change this?
