I am planning on getting to Diablo sunday mid morning, too late to race, but want to get some riding in as a last chance before the end of the season. I just checked out the course so I understand that there will be no riding on those trails but my question is will Tempest still be accessable or is there no way to exit due to course location, and other than that is any of the backside available to RIDE? Thanks for the info. Dave
