Kind of short notice, but since it seems nothing got organized in Houston for Tartan Day, How about a kilt night at the Houston Tilted Kilt to mark the event?
Strap on the colors, tell your friends, and lets get together for a little Tartan Day celebration at the Houston Tilted Kilt. This Tuesday, April 6th, 7PMish...
Hope to see ya' there!
