Well, back in ‘69 (you know, back in the last century) I spent the night in the Naval Hospital there after getting sick underway and having to transferred to a tug outside the harbor at night. Strapped in a stokes stretcher going over the rail. YIKES!
spooky experience - but on the bright side; had you fallen, it would be into warm water.
we enjoyed PR. Living in a small town outside of San Juan, we were probably the only gringos and we were incorporated into community life even though our knowledge of Spanish was limited. Good folks.
