Is it possible to get a taxi ride on the New Hampshire coast at about two in the morning?

Well, the deal is, I'm writing a book that involves two guys going on an "outing" at around 2:00am. It would be convenient to have them call the local taxi service for a ride, but not absolutely necessary. The section of the book that takes place in Hew Hampshire is very short, and as I am not from there myself, I find myself in search of this information. Anybody able to help?? Thank you!
