If it is not too late, there is an instructor from Sports Chalet that Dr Bil has been raving about. You might give him a shout.
Hey, read my post... I didn't say the instructor WAS from Sports Chalet, I said he might have been based on the labels on some of the student tanks. I'm not dissing Sports Chalet, only the instructor.
Dave, if conditions continues like they were today, your family will have an outstanding time. However, if they kick up tons of silt, I'll be on YOUR case (just teasing).
