hands down, you take that offer. it's over double what she is making. being from the buffalo area- niagara falls specifically, there will be plenty of things to do. it just depends on what she is into. the snow is rough but having the increase in money, she should be able to budget and save a lot of money. if she doesn't like it there grind a few years, save and move on.
i don't live up there now cause of the winters but i go home a few times a year. was just there 2 weeks ago for the bills-patriots game. everyone disses the area, but once you get here, you slowly start liking it. good food, people and buffalo gets a lot of entertainment there. concerts, shows, museums and stuff to do. during the spring summer months there is a lot of great parks, places to visit.
i'm of the mindset, anywhere you go its what you make it. if you're a boring person, you're gonna be bored anywhere you go. if you into different stuff beyond just nightlife its plenty of stuff to do.
it will be a culture shock weather wise mainly, but you adapt and elevate yourself- look at the big picture.
but i'm someone who has lived in a few different states, if someone scared to leave their comfort zone, you can't complain when you never achieve anything. everything is uncomfortable until you make it comfortable. you learn about yourself also and build resilience.
