Does the traffic die down after a certain time, i.e. 6pm? If you head thru 522 at 6pm that would make for about a 7pm Index arrival wouldn't it? With headlamps, on rock climbing time could be extended thru about 9pm even though there isn't any sun right?
Yep - the traffic does seem to be better on 522 after 6PM Erik was right about going through Duvall & Monroe - it CAN be lighter unless the lights are out.
Have a blast!
