She's the most famous automotive spy photographer, and probably started the entire spy photography business. Everyone else that you see has followed her lead, although she is very respectful when trying to get her spy shots, as opposed to some others that will run you off the road to get a shot. She's also an activist for ALS and does fundraisers. Some car makers have even donated items to her for charity auctions.
I've never met her personally, although some coworkers have and they've never said a bad thing about her. She's a well-respected person in the industry and probably has some interesting stories to tell. Where ever she goes she always posts pics of cars she sees at cruise-ins, shows, meets, etc. She genuinely enjoys cars and, for lack of a better term, the thrill of the chase.
