Well, you should've come over and given me a big Texas welcome! I was on a 90 min cruise (didn't want to dip into my 2nd scrubber) and finished up my "PADI Braille Diving Certification"
Didn't really know I was at the silo's until my hand hit something I thought was a rock. I brushed the silt away and saw the grating . . . YEE HAW. Seemed after you hit 45ffw, it was lights out and swimming in a cloud. I had lots of places where I could only fuzzily see my computer & compass @ 6" (you must've seen the same). Anyway, after swimming around for 1hr, I decided to head back (a 30min trek) & was pleasantly surprised to have made it back to within 3' of the stairs I left from.
Seriously, next time you see me stop by. I know I'm a Yankee, but Aquatrax seems to think I'm OK for one.
