Skiguy,
I'll soften up my statement but only by a very small amount. You are totally correct that if you can travel to destinations (like the N Conway area), you have a better chance at finding both a) decent gear selection for nordic backcountry gear and b) shop staff that uses it on a regular basis.
Next time you travel outside of N Conway, I would invite you to go into other retailers and play dumb and go through the motions of buying stuff. The number of folks I've found at Boston or Burlington, VT based retailers who actually use nordic backcountry gear is very, very limited.
Please note.... this is not to denegrate retailers in anyway. The key for retail viability is turnover rate of stock and nordic backcountry gear is a low volume set of gear. I wouldn't expect to find retailers (outside of destination towns like N Conway) who would be able to attract hard core users as employees.
Just to doubly reiterate the point, there are some really good knowledgable shop employees out there. It's just that the chance of finding them when you walk off the street is very, very small.
Note.... the same problem exists for buyers of touring bikes. Most shops deal predominately in racing bikes, mtbs or bmx bikes. The number of shops that have employees with any meaningful touring experiences is just about nil. I would never send somebody who is looking for a touring bike out with the advice of just find a good shop to help guide you.
