Two years ago a local place wanted to book us for a Saint Patrick's Day about four months in advance. On hearing we were already booked, they promptly booked us for the following year. We've been invited to play for the 50th anniversary of Arizona State Parks. To make sure we would be available, they booked us 14 months out. If you want a particular group on a special day, it doesn't hurt to make arrangements as soon as possible.
Not something that happens very often to us, but it's nice when it does.
We've just set up a web page. Please check us out at harpytrails.com
Scary but exciting.
