It can be very scary and it is a dangerous job, but if you really stop and think about it, slipping on a wet floor, or falling off of a ladder can kill you or many other things you don't really think about. This is not a job for everybody and I would never pretend that it is. I feel like its good experience to travel and see new things, but just be smart and beware. You can find trouble anywhere if you look for it.
I've driven coast to coast which is about as long as it can be. I hated the long travel side at first, but it grows on you. There are good home eveyday gigs too, but you just have to find whats best for you if you get into it.
