I attended the 2008 Veteran's Convoy today that began at the Clark County Fairgrounds Event Section just north of the I-5 and I-205 interchange.
There were some really great convoy vehicles all decorated with a patriotic theme. There was judging of the vehicles with trophies and blue ribbons given to the winners.
My entry was, ahem, a tad bit controversial, but that was for a valid reason, IMO. I'll post pictures of it later.
