Hours do suck, pay is marginal, but its never boring.  It takes your full concentration at all times, in the matter of seconds you can become a 17,000lb sled going down the hill fowards , backwards, or sideways.  Building shit is cool, cabs are climate controlled and have mp3 player hookups.  Blast the music and relax, wouldent wanna do anything else in the winter, very  rewarding job.
