Detected for a few hours in Seattle

Just tried my sisters backyard.   It was so bad I only found 1 pull tab :o(     Found 3 cents, 2 were ZLincolns and the other a memorial.    There is a school 1/2 block down and a nice size woodchip covered playground about 5 blocks away.     Walking there wouldn't be a problem, walking back up hill would be though  :P
