Attire

This is a rendezvous, not a formal wedding. So feel free to come as attired as you would to a special Saturday family picnic or potluck, where horseshoes, Frisbee, and full-contact football are likely to break out.

If you aren't sure what sort of attire this implies, here are some sample images of such.

Really

For the rendezvous, cheerful, relaxed attire is fine. If you want a theme make it Western. A cowboy hat would suffice. If you are from Nashville, feel free to load up with Rhinestones. Just don't wear them into a local cowboy bar.

And More Reality

Rocky Mountain weather is varied. It could be in the 90s on July 8, so bring clothes for non-humid, hot weather. There could be a thunderstorm or two on July 8. Then for a moment it could be both chilly and humid. Most of the time the evenings and nights get quite cool. Sweaters and jackets are advised. If you plan on doing outdoor stuff, such as visiting Yellowstone, be prepared for all sorts of temperatures and weather.
