I want to share part of an e-mail message I got from Jeff.
===============

Thank you for the congrats message.

The top of Mt. LeConte has the state line running through it. I was 10 feet into North Carolina for number 500. I did do numbers 499, 501, 502, 503 and 504 in Tennessee though. As I probably mentioned, this was the favorite place of my late mother. She would hike to the top with my dad when they were 67 and 69 just to have lunch. It is a rather extreme hike but she loved it. So all the planning for 500 worked out great.
It is rated a 4 1/2 terrain and perhaps we should make everyone do this one before they rate their terrains and they might change their standard. Due to ice and snow we took the “easy way” to the top – 11 miles starting at 2900 feet to 6600+. The trails were coated in ice and we considered turning around but kept at it. On the cliff trails with dropoffs that were coated with ice, there are steel cables in the rockface to hold onto. More then once these cables prevented a quick trip down. My newest son-in-law decided that we were all nuts but he struggled through the hike.

So 500 was very special and I am sure number 1000 will be also.
