I saw the occasional man-o-war as well. Lucky for me I was close enough to catch a "flangae" across my knee, I have a nice little itchy red gash like mark now.
you know what....I thought i was hallucinating...But, I think i saw a man-o-war as well. But there are tons of red jellies all over. I still have a itching/burning sensation all over my legs and arms from 2 days ago...I got it good..
