N to S From Mexico to Oregon Border California is roughly 750 miles long. East to West it's about a 3.5hr from the Coast to Nevada.
Hills in Texas

Crossing to Nevada you drive over a 7000 ft pass, the Mountains are vastly taller than that and I forgot to mention the Olympic caliber skiing that is on the mountains.
And why I don't like Texas, it't hot & humid in the Summer, completely miserable. Your winters are pretty bad too, not a fan of Thunderstorms in the N. Texas area or the Hurricanes in the Coastal areas, I think it snowed in Dallas this year too. So miserable Summers and Winters? Why I hated the midwest when I lived there.
Average winter high is 60, Average Summer high is around 78.
We rarely drop below 32, maybe at 6am a few times a year. and rarely hit 90 or above in the summers.
Lets talk crime rate. Dallas, Houston and San Antonio are all in the top 4 for worst crime in large cities. San Jose at over 900,000 population is the safest big city in the nation.....
I have Laguna Seca & Sonoma raceway less than 1hr's drive away, wine country to the South in Santa Barabar and to the North in Napa/Sonoma.
Yosemite is a 1.5hr drive East.
I've been to Alabama, Iowa, Michigan, Illinois, Massachusetts, Georgia, Arkansas, Missouri, Oklahoma, & Colorado . Only place I liked as much and felt as homey to me was Boston and Chicago in the Fall/Spring.
I liked Dallas, I really did, but damn that weather in the Summer, you all were friendly though and that cost of living is super nice.
I think if the price was right, everyone of you would move to Cali. Aside from the asinine cost of housing, this place is more than alright.
