The wife and I are planning on being there. The forecast on channel 13 last night was for 80* and sunny for Saturday.
From I-5 either north- or south-bound, take the NE 145th Street exit (exit 175) and turn west. Go approximately one mile to Aurora Avenue North. There will be a Las Margaritas restaurant on the left. Turn left on Aurora and KV is a block down on the right.
The Cruise-In is Saturday night, btw, but the Mustang Life people do one in Puyallup at the Krispy Kreme on Fridays.
