worth moving for a promotion..?

Money won't make you happy.

Yes it will!!!

I was all set to pack up and move to a place that I love (St. George, UT or Vegas area) but them my work promoted me and gave me a raise and the chance to do something that I love 8 hrs a day (building/fixing things and welding) I am in charge of plant maintenance and I also do custom welding, fabrication, R&D work and once a month I get to drive down to St. George and Vegas for work.

The money makes me happy and convinced me to stay in this wet, cold, shitty state that I can't stand until something better comes along.

People that say things like "money doesn't bring happiness" are full of it! If that were true you will be just as happy if we take all your stuff away and give you a cardboard box to live in during a snow storm.

Money makes the world go around! If the offer is enough money that you will be better off there than CO (factor in the cost of living). Go for it, if not then stay.
