My son and I decided to wing it and drove (4 hours each way) to the show. We had a great time looking at all the bikes, and going to Hoover Dam, plus a couple of other side trips. Glorious winter desert weather. I only saw one Laverda, an RGS on display in the entry area. There were many Matchless and AJS, it seemed like there were more of those than Triumph-Norton-BSA.
I saw a 1911 HD 'Silent Gray Fellow' and my son posed for a picture - the same model his great-grandfather is pictured on below, 111 years ago.
