From Dr. Powell's son Rich:   "I stumbled across your site looking for pictures of my dad, Lyle Powell, and lo and behold! your images turned up on Google!  Here's just one photo of dad in the corkscrew at Laguna in #197, 
Crocus, my favorite car of his.  I'll dig around for more if you would like me to....(Yes, please do!  TM)  Thanks for the great memories!!"
