DAVID PANNELL I spent last weekend atop Mount LeConte in Tennessee’s Great Smoky Mountains. I was joined by my wife and our son, along with my brother and his wife. Though you may find it hard to believe on this mild Easter weekend, it was 17 degrees and there were seven inches of snow on the ground. We, along with about 25 other paying guests, spent the night at LeConte Lodge – a 1930s-era cluster of cabins at LeConte’s 6,593-foot summit. The cabins have no electricity or running water.
