nailed it. I think its a CPO.
Change of subject. For all the folks that do this for a business. How many miles do you usually claim on your taxes? (of course, I have perfectly recorded all my miles and in a legal and orderly fashion just like the IRS would expect and I am not asking this for any reason other than an educational purpose -- TAKE THAT NSA listening and reading everything we do and say).
Doesn't being an attorney already qualify you to deduct a percentage of your mileage...who is going to question that?
