Well, I believe Dave was at the last two Winston shows...autographing books etc. and personalizing some of his art. If you buy one of his prints, he will personalize it by adding an additional pencil sketch and your name, at no extra charge. Pretty nice and a lot of folks perhaps don't realize he does that....just ask...or leave the print you purchase with his "assistant" and come back and pick it up.
Last year, or the year before, I don't think he made the Winston show on the first day due to bad weather on the commute to NC...but he was there the second day, as I recall. If you catch him on a fly tying demo or working on a fly, he has always been very willing to show some techniques, tips etc. My tying guru for the store, Mickey Reavis, spent a couple of hours with Whitlock at a show in Charleston...soaking up the knowlege and experience.
Whitlock and a lot of the other "greats" are even older than us (hard to believe I know) by quite a few years....so now's the time to say hello; pick up a piece of art; have them autograph a book etc. The Winston show can pull in the big names for a variety of reasons.....Asheville?..not so much...but a lot of local, regional knowledge to be had.
