Our back yard is like 40x40 (if even that) but it keeps giving up more stuff that I didnt hit the last time. Today I found 2 quarters, 1 dime, 2 nickles and 5 pennies... along with the outer shell of a hotwheel and a weird watch.
Man, that's a pretty cool looking weird watch cpt, I like it. you've inspired me to go out and hunt my own tiny back yard, haven't hunted it in quite a while, gotta be more goodies there.
