Well there are lots of things to consider beyond geographical attributes.
My observations from of Both States:
Driving time: If you live in central texas, it takes and hour at least of 70mph highway driving to get to the next town. In Colorado, it takes an hour of 30mph of windy, mountainous roads to get to the next town. Unless you are on I70.
Politics: most people in Colorado are died in the wool, Democrats. Many a time during my stint in Aspen, the people would put an animals life before yours and never blink. Bush is EVIL! and if you leave your dog tied to a tree, in the shade, in 70 degree weather your neighbors will have fit and report you to Animal protective services. Lots of pot smokin goin on there openly AND no one will say hello to you if you say hello first. And what ever you do DONT disagree with them.
In Texas, people are died in the wool republicans.
People say Hello to you first, stop you ask you where you are from, and want to know all about the weather there. ( of course they are secretly hoping that you will take the next bus out of town). Bush is OK.( I did not say great, or "god's gift"... just OK.) People love their pets here, but keep them undercontrol or they might get shot by the neighbor. People smoke pot, but behind closed doors, and cant wait for their Mexican to get here, cuz therz work to be done. And what ever you do Dont disagree with them.
Cost of Living: Property in Colorado is getting very hard to come by. In Texas there is always a rancher splitting up the back 40. In Colorado, you get paid more, but it is relative because it costs ALOT more there to play, eat, and have a roof over your head, ANd you have to pay State AND Federal Taxes. In Texas,there is no STate tax, but substantial property taxes.
Food consumption: In Colorado they drink Pepsi and Coorse beer. I can not think of a single ethic food that they perfect, outside of GOURMET.
The Gourmet food is divine.
In Texas they drink COke....well it is all Coke, you have to tell them what kind. Shiner Bock Beer and dont mess with their BBQ, Chili, or Mexican food, because you can not improve on perfection.
Employment: In Colorado it is an employee's market! You want a job there, you can get one anywhere you want and at what ever status quo you need. In Texas, you have to work the good ol'boy system. Job openings are few and they are looking for the BEST qualified person, so have your resume up to date.
Want to start a business there: either place, it needs to be location, location, location. Look for a place that has a population over 4,000, and make sure there is not a similar business in a 40 mile radius.
As far as plumbing goes, your husband will always find work, even if there are 8 other plumbers in the same town, and even if he is unliscenced. People dont care, they just want to be able to flush the toilet.
