Here's a good site for them also:
I love the Internet! There is only one thing I've never found on the Internet; The complete rules, including all measurements, of the game of horseshoes. I've found pieces, but the entire package is never there. Pit distance, depth, peg height, throwing location rules, leaners, touchers, toppers, the works. All on one site.
Betcha you can't find it!
Weird, but true.
(Now watch four people find it...Ha!)
