Jamie,
Another goooood reason to go to Las Vegas the weekend of the CC>CC Convention. ---IS---That SAME WEEKEND as the CC>CC Convention at the Riviera is the national STAR TREK CONVENTION - Aug. 9-12 at the Las Vegas Hilton in Las Vegas. Your son wants to go to the Hilton star trek experience. Why not take him to the Star Trek convention. For a experience he will NEVER forget. ANYTHING Star Trek will be there including a lot of the orginal cast members. A lot of the "Treckies" as the star trek collectors and admirers call themselves will be dressed up as the different star trek people that the actors played--Data. Capt. Picard, Cloganons, etc. And many exhibits too, as well as things to do there.
AND at the same time you and him could fit in the CC>CC convention. He could learn all about silver strikes that you like to collect at the same time.
Look up Star Trek convention on your computer for information on it.
