I was watching a show on TV today and they had an aerial view of the HOLLYWOOD sign on the hill near Los Angeles. Has anyone flown that hill? Looks like a great spot for DSing. ----- Original Message ----- From: "Paul & Rickie Clark" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, November 21, 2001 6:16 PM Subject: [RCSE] SLOPE FACE CONDITIONS
