2009 Christmas parade (http://www.clearlakearea.com/about/BoatParade.asp)
Both you and your kids will enjoy this, starts at 6 pm.
48th annual event, started by Red Adair and friends way back...
One of the best areas to view is Seabrook Shipyard, if you can get a parking pass...
From the website:
"Ring in the holidays with this Clear Lake tradition. More than 100,000 people traditionally enjoy this event from land and from hundreds of boats anchored throughout the Lake The parade features more than 100 brightly decorated power and sailboats that will traverse the Clear Lake channel from the South Shore Harbour Marina and the Nassau Bay Lagoon to Galveston Bay."
FYI - No passes available this year. They are only allowing cars with "Seabrook Marina" stickers on-site. So have your friends park under the bridge and pile into stickered vehicles.
