Travel to the Pacific/Western!

Hello, I'm Hernan from Buenos Aires, Argentina.
With some friends plan to travel to the West of the US.
We go events NHRA Western National in Seattle and Bonneville Speed Week in Utha.
The trip would be from 5th to 22th August, we arrived and departed from the Los Angeles International Airport.

the planned route would be:
LA - Seattle - Yellwostone (a bit of nature does not hurt), Salt Lake City - Bonneville - Las Vegas - LA

Yesterday (07/20) announced the cancellation of Speed Week by problems with the salt layer.

My interest at the forum is whether you can advise me that other automotive events/cruises/meets/swaps/drag raceways/builders/etc can visit along the route or nearby.

It would be our pleasure if any forum user we would like to drink a few beers, watch their cars and talk about drag races.

Thanks, Hernan
