Called the box office number listed on the LiveNation site prior to leaving to check on the status of the show - it's a non-working number. Left DC around 6:15p (late, I know). Traffic was very heavy on I-66, esp. nearer to the exit for Nissan. Took exit 44 and were stuck in traffic on 234 for at least an hour. Wellington road was apparently flooded to the east of the Pavilion, so traffic was diverted over to Linton Hall to approach from the west. We gave up after another hour or so crawling along with hundreds of others, figuring we'd never get there in time to see Radiohead. A huge (and expensive) disappointment - this is the first and last time I buy tickets for a show at Nissan.
