Tax season is over - what's this pile of Vegas receipts?

Tax day is in the past now, but taxes are an unending chaotic mess. I filed for an extension on my taxes, just to give me some more time to sort it all out, and it is a good thing I did. When I was cleaning the office back up after working on taxes for other folks I helped out this year I found out that I had a few piles of receipts from that business trip to Las Vegas that had not got entered into the spreadsheets. Oooops! Okay, so now I have some time, I'll go ahead and get those entered into things and see how that changes my tax situation.
