Hi,

I was driving when we launched and recovered Alec's
sub. As a result I do not have actual pictures of the
act. However I do have a nice shot from up on a hill
looking down on the marina parking lot. The trailer
tounge was like four times longer than any other
trailers. :)

I'll work on getting my 2006 PSUBS Convention pictures
on the site.

Regards,
Ray
