Oshkosh - I am super jealous. Some day I will make the pilgrimage. Some day... Fire Safe - The one thing that always survives a fire is your freezer. Double-ziplock-bag your important docs, put them on the top shelf of the freezer, or stand them up along the wall inside the freezer, and even if your house burns to the ground, your docs will be fine. (Proven, sadly, by friends of mine.)
Plus 1 to these bits. Regretting not going with my squadron when I was in Civil Airights Patrol. Haven'the really nerded out on planes in a long time, aside from peeks into #aviation. Enjoy it, Eng! Throwing in the lot for the fire safety zip locks as well. Keeping safes at hone are ten-fold easier than the hassle of a bank, especially if you need documents in short notice on your time.
