Doh!

Clearing all of the tax-related papers from my desk, I discovered that I overlooked the interest on a home equity loan we took out last spring in support of our tragic garage debacle.
We paid about $1,100 in interest on the loan, all of which is deductible under current tax law.
So I fired up the TaxCut software and plugged in the new data to determine if it's worth it to file an amended return. Turns out it means another $200 or so on our return, so I guess I'll go after it.
