Thanks for a interesting and scary post! Your comments on your website do bring up a point I've been wondering about though ... what is the fog horn I've been hearing (heard it this morning BTW)? Is it the one a certain doctor in town owned and citizens who didn't like it banned together and got it dismantled?  Love listening to a fog horn on a sleepy morning ... (also, sorry to go off-topic.)

I am pissed, I am not hearing any fog horns and I loved when I used to hear it back in the '90s!

Darn, I missed all the fog and yucky weather while I was sunning and enjoying the heat while on a glorious day trip to Fredric. Very cool pic!

Hey, BeastofBurden. Good point about perspective. But check out this harbor footage from Friday. First, it's totally like watching "Theodore Tugboat," a PBS show I loved more than my kids did. It also lets you compare the last-second jigger of the Orinoco as it came out of the fog with the leisurely jigger of the Canadian Olympic later after the fog lifts.
