According to the schedule Pam saw at Red Rocks yesterday, sound check is scheduled for 4pm.
And here's the e-mail V. got when she asked about the camera policy for tonight:
We haven't heard anything different than our general policy of allowing small, personal cameras. No large lenses, no detachable lenses, no pro cameras. However, I have known band's to change their minds on the day of show. We try to post that on the roads and at the bottom of the ramps when that happens.
