Be advised if you are coming that the Seattle Rock and Roll Marathon is going to be held also on June 26, in the Seattle and Tukwila area. The race starts in the north Tukwila area at 7am by BECU and finishes at Qwest Field in downtown Seattle.
The Renton Community Center is near, but not close enough so that you should not encounter road closures if you stick to the I-405 and Maple Valley Highway.
Do not try and cut through Renton or Tukwila the morning of the taikai, or you may be very sorry.
