This is a great place, it was a very valuable "tool" when I received my first big KX. Lots of very helpful and honest info.
BTW ... GwCrim ... just tell the wife you have a surprise for her ... 3 days and nights in beautiful Yuma Arizona (lol)

... You would be set! she can shop at WallyWorld and you could take the 10 mile ride to the dunes. Ummmmm..... she just might go for it.

Or, you could always get side tracked on the way to the Grand Canyon and slide into the dunes from there. If you want it bad enough, you'll find a way!
