Reanm8er, thanks.... I took care of a pool back in the late 60's.... it was 12 ft at the deep end, and I usually got the coins on that end, not too many kids could stay down long enough to find anything, but, I could... lol It had a boardwalk around it, but, it was only about 3 ft high... crawled thru many spider's webs to find a couple dimes under the soda machine.
