Hey, what about all the Mor....

Um, seriously though, I assume the close proximity to good mountain biking, and various other outdoor excitements will also help keep you busy and happy for at least a year or so.

In fact, if Kelly warms up to it, living in Utah might even be a sweet permanent arrangement for you two.

However, I have you two pegged in my mind as more "coastal" types and more "large cosmopolitan city" kind of people. But I'm often surprised at how malleable people are -- and besides one winter of Utah powder just might make you decide never to leave again.
Besides, with the (comparatively) lower cost of living, your animation income, her OD income, and your para-sporting gig, you guys could be quite possibly the world's most unconventional yuppies.
You know: white picket fence but skateboard halfpipe in the back yard, etc.

On the more practical side, I would try to make sure that you can visit her in Boston half a dozen times in the next year and that she can come visit you in Utah a half dozen times as well. That way you can still keep sharing "each other's worlds".

I, too, once (long ago) carried on an LDR with an East Coast girl (Boston, as well). But since we eventually failed to make it work, I feel that any more specific advice from me on this subject would be worthless. So hopefully someone else can address that aspect. Especially since you guys have been together so long that this year apart will be much more like an extended separate vacation and less like a big strain on the relationship.

Also, since I doubt I am much older, wiser, or sagelike than you, I hope that you at least gained some small value from my ramblings.
