Shoot – you know you’re big time when they tour you with your publicist!
A lot of people’s “tours” are paid for on their own dime. Next step up – you stay with friends. The rung after that – the publisher gives you a sum of money and you do with it what you can, preferably cheaply so that you can spread it out further. Up above that – an escort who drives you places and a nice hotel to spend the night in. I’ve done the latter a few times. But I can’t imagine being a big enough deal to tour with a publicist. But then again I’m not Barbara Park.
