Your invitation is a GREAT idea, but, like some others of us, my guess is that the years have caught up to Len - he will turn 75 in a couple of months. He, however, could, I am sure, teach lots of folks about welcoming either newbies or out-of-towners to a show.
Several years back, I had a premonition about Michael Fultz. We had been communicating for some while via email, and I just got the feeling that Michael would not be around much longer, and I went to Chicago to pay my respects and thanks to Michael. I walked into the show room, and the "hosts" were nowhere to be found, but Len was the first person I happened upon. He pointed out Fultz to me, and was otherwise both gracious and extraordinarily helpful in helping me put faces to names. In addition to his many other talents, he was the model of hospitality. I have tried to pay Len's behavior forward at our show in Dallas.
It's taken me a few years, but there are some special folks in Dallas: Pete, as Len wrote, John Jenkins, and Mike Walker - the show boss. As you know, I needed some help this year, given my mobility issues, and Mike called me to make things as easy as possible. Much appreciated from both you and him.
Len, you would be most welcome at the Dallas show, and I bet I could find a bunch of people who would be glad to treat you to that bowl of chili to thank you for the many kindnesses and lessons learned over the years. If your old bones preclude that, we will think of - and miss - you.
