Well, I turned 58 the end of May. Never served on a Sub (Army, Airborne, 66-70) but I have toured the U-505 3 times and would do it again. My first tour of the U-505 was some 48 years ago and it hooked me on subs for the rest of my life. My first Sub-sim was Seawolf or 688 Attack Sub, I can't remember which was first. Don't laugh, ya'll are headed for CRS sooner or later if you live long enough.
