Quick update: just met Susan for 2 hours yesterday. Holy hell. Run, don't walk. She's still in NYC and will be in Jersey after that. If you have the opportunity and don't do it, I just don't know what to tell you. She said she's planning on a mini-tour like this about once a year so if you're not in SoCal, this is your chance.
Her photos are a good representation, but she is much bigger, harder, and more dense in person - even in her off-season condition she looks fantastic.
DO IT.
