I agree with some of these things. Second homeowners can never be a local, regardless of whether you worked there 20 years ago when you were in college. Also, just living there doesn't make you a local. It takes a few years. Here's some sure fire ways to know if you're a local:
1. Directions like these make sense: "Go down the street past the old IGA, turn at Sam's place, and go up the road until loops back toward the ridge."
2. Your friend's names are things like: Dumbfy, Pigger, Weeds, MJ, Coach, and The Green Midget. You've known them for years, you're not entirely sure of their real names, nor have you ever really questioned it.
3. You came out of the bar and your car is gone. You're not worried because you know a friend either had your spare key or knew where to find yours. He probably needed to get home more than you.
4. There is a barter system and you understand it. You know what can be bartered for and what can't.
5. The conversation you have the first year you live in town: "Man, I got these sick new sticks. They're rockered and slice through the pow like butter. I mounted the bindings chord forward to get a little more tip pressure."
6. The conversation the second year you live in town: "We skied Alta Chutes all day. It was good, but I think I need to get into the backcountry tomorrow."
7. The conversation the third year you live in town: "This season is a bit rough, it's definitely not as good as a couple of years ago."
8. The conversation the fourth year you live in town: "I sure wish Shamus' was still open. That was a great bar. Anyone seen Freddy lately?"
9. The conversation the fifth year you live in town: "That's b*llsh*t they wouldn't give me a comp ticket. Seriously, I even offered to trade him my old derailleur. There's no way I'm paying for a ticket."
10. The conversation the sixth year you live in town: "My homeowner association is thinking of raising dues again. I can't believe it. And they're plowing half as much as last year! I heard a rumor their thinking of doing an assessment."
11. The conversation the seventh year you live in town: "Those idiots buying the second homes up in Snowy Peaks are just gonna screw us all over. There's no way they're worth that much money."
12. The conversation the tenth year you live in town: "Yeah, we're thinking of spending a few months with Ed and Sandy down in Page. It's just so cold here in the winter we'd love to get away somewhere warm. I'm so jealous they sold their place and bought that houseboat."
13. The conversation the twentieth year you "live" in town: "We drove up and went skiing this weekend. We went to the old K Lift pub and Coach was still there. Apparently Weeds moved to California with MJ. Dumbfy lost his property management job. Those morons at that company don't realize a good employee when they've got one."
