huju,
“I sense that Gadolha and Common Saychel have doubts about Chabad’s readiness to raise a minyan. And yet Common S tells us Chabad did help him/her raise a minyan.”
He did not tell us that – he said that he posted on godaven. From my personal experiences with far-flung Chabad houses, making a daily minyan is not one of their biggest priorities. I’m sure the shaliach will try to help if requested, but you should ask what the chances are of success.
I was in the Smokies a couple of summers ago on the NC side of the park and was pleasantly surprised to encounter more than one other frum family during our stay. I had never seen other frum people there before on previous trips. Chol Hamoed is probably a bit tougher to swing given the distance from frum communities (Atlanta is probably the closest and is several hours away).
