Gary,

Congrats on your win! They like to see as much documentation as possible of the losses you use to offset your win. I seem to remember reading somewhere that the losing stubs from your horse race wagers were considered good documentation.. Those horse race stubs with footprints on them are unacceptable.. considered suspect for some reason (Grin).. and as a good Californian, I am sure you have plenty of losing Lotto and Scratcher tickets laying around.. It may also be possible for casinos where you used your comp card while gambling to print up an accurate record of your losses during the year. Glad to see you win the big one!
