I think you will find all the major players at both but no doubt Reno is bigger. The Dallas Safari Club has no intentions of getting to the size of Reno. Our booth cost and exhibit hall entry cost are much less too. We are some 2300 members strong and SCI is much, much larger than that.
Many like Dallas better as they don't feel the pressure that you sometimes feel in Reno...Dallas far more laid back and everyone tries to make you feel welcome. You will have a great time at either. There will be about 650 exhibitors at Dallas. Probably 1200 + at Reno.
I will be Booth 229 at Dallas, Booth 202 - 204 in Reno and don't know my Houston Safari Club booth number yet.
Do them all and see which you liked best!

Dallas would get your attention.....Reno will blow you away!
I'll be at both.

Haven't been to the big show, but I have been to Dallas.

The Dallas show is just wonderful, large enough to keep your attention, small enough to be able to visit with old and new friends. I look forward to the event each year.

The one thing you will not find at the Reno event is the JudgeG and Ray Show!

The Houston show is not as large as the Dallas show, but is making progress. It was great fun last year.
