The Blaggards and the Flying Fish Sailors are doing a free concert on Discovery Green downtown at 6:30 Thursday night.

I went to the concert last week, and it's a great venue - on the lawn across from the George R. Brown. Bring chairs or a blanket. Bring your cooler - just no glass permitted. They have Saint Arnold's available, as well as other libations. Parking meters shut off at 6 PM, so be sure to arrive after that. Lawrence's friends got a ticket a few weeks ago.
I'll be there. Hope to see other Houston rennies too!
