Just watched the last scheduled news conference. They are reporting now that +1000 structures were impacted, most of which were destroyed.
Here is a map that shows the extent of the damage and where a structure was partially or fully destroyed.

They are now able to show more photo's of the extent of the damage. Really hate to see this.
I agree with a previous post, if you want to support Gatlinburg plan on going back for a visit since tourism is their bread an butter. Given time I believe the community with come back stronger then before.
