Re: [PSUBS-MAILIST] acrylic domes

Carl - I'm half Italian and half French Canadian.  Not only am I predisposed
to speaking with my hands, I'm a congenitally hopeless romantic!  Of course,
don't ever expect me to show up anywhere on time.

The way I figure it, a whole day of submarining should be capped by tying up
the sub to a log boom, breaking out the vino on deck and watching the sun go
down.  Maybe watch a shooting star or two.  Go below and be entertained  ;-)
My wife loves boats.
