I've mentioned this before, but I've met a few SEAL's over the years. Their west coast training area is on Coronado Island (San Diego). I grew up near a Marine base, by Oceanside, so have come into contact with many navy/marine personal. Met ex & active SEALs mostly through friends in social situations (bars & restaurant..and parties). Some through training.
Biggest surprise, when first meeting a SEAL team Member, was that a few were in their early 40's. Late 20's to mid 30's seem the average age. Guess experience can make up for age sometimes. Some try keeping that old fighting edge by working out. A very few are into Tri Athletes events. Hundreds of Tri Athletes around San Diego and North County.
If going to some bars around Coronado, where duty and retired SEALS hangout , might suggest McP's, Danny's & Little CLub. One in Imperial Beach, think it's called the Plank or something like that. Also Point Loma offers many good bars, but SEAL's tend to stay among their own or some select civilians. EX-SEAL members look just like anyone else;long hair, buzzes, beards, short, fat, etc. Active members have a distinct look, hard to put into words.
