Here's what I can tell you. I'm coming up on 10 years here. Weather is spectacular from mid March til early June. Then turns very hot thru August. As long as it is 105 and lower I can golf 18 holes and not even break a sweat. We were at 70 degrees until the first week of Dec and now it has been 'cold' for the past 3 weeks (about mid 50's to 60's during the day and low 40's at night). It does get cold and I've actually built a snowman a couple years ago so we do get snow but rarely. Weather is pretty awesome in my opinion.
Everyone thinks Las Vegas is just the Strip. That is far from the truth. I have lived in 2 great neighborhoods, one in the Northwest section of town (Lone Mountain area) and it was pretty close to anything you needed and about 35 minutes to the airport and 20 to the Strip for when family and friends come. My new place is more centrally located and only 10 minutes from the strip and about 20 minutes to the airport. It actually has a small town feel to it as long as you aren't in the center of it all (Strip and downtown areas).
Food options are endless. We have a 9% tax but property taxes are miniscule. I pay half the taxes I did in New Hampshire and my house out here is worth almost 4 times as much as that one.
You can fly to Cali in 50 minutes, the airport is easy to navigate and fast check ins as well. I flew to Reno last week in 50 minutes as well. You can drive to Mt Charleston in an hour and see snow if that suits you (it literally lasts up there until mid May). If you want to drive to Cali it is about 4-6 hours depending on where you want to go.
Crime happens here, but I have never witnessed any or even been close to any so far and I work in the most undesirable place in the state (North Las Vegas).
Healthcare is pretty good, haven't had any issues there (actually went to the ER yesterday for what I thought was a heart attack). My Dad comes and stays with us from Upstate NY from Dec to April and we haven't experienced any issues with him as well in the healthcare industry. He actually came and rehabbed here a couple years ago cuz it was better than where he was in NY.
We are becoming the sports mecca of the USA with Pro hockey, football, and the A's will be here in a couple years I think.
Like I said, 2nd best decision I ever made, good luck on whatever you decide Wild Bill!!!
