Myra, go to www.weatherunderground.com & search South Dakota for Mt. Rushmore.
You may also want to go to www.travelsd.com for weather info, among other things, on South Dakota.

The weather underground? Weren't they something like the Black Panthers in the 60's?

Wow: how did you manage to develop your psychic abilities to this degree?

I suspect that Wow cheated and looked up the OP's other threads, one of which was posted shortly after the OP for this thread and which specified "Hi, What do you think the weather will be like the middle of August? We will be in at Mt. Rushmore. Thanks"

But that post got only 2 replies.

Hey, Litespeed Chick (nice name!) & Anonymous: Not psychic or cheating. I just happened to remember when I read "What to bring" that Myra had asked about Mt. Rushmore...somewhere, sometime. I remembered the name Myra53....but that's another story!
