This is just my opinion and others may differ:
I was able to attend the tackle show because of a customer changing his trip from Sat. to Sunday because of high wind.
I went to the Arlington show on Saturday. I rode with a friend, another friend paid for parking, another friend, a guide with a booth, provided me a free ticket. My total cost was ZERO, and that's exactly what I got from the show ZERO. It was the biggest bunch of nothing i have ever experienced. I haven't been since the show was moved from Big Town in Mesquite over to Arlington probably five years, maybe more. Very few vendors, boats, or guides. the show was nearly half the size of what it use to be. If someone would have given me $1,000 to spend while at the show, yeah fat chance, I would have had it all when I left.
Was this the way the Houston show was? I hope not. Maybe not since the Houston area has a lot of saltwater stuff plus the freshwater.
I do feel this is somewhat tied to the economic downturn and don't look for it to improve anytime soon.
