Ron, it is my pleasure to attempt to answer questions on this and other forums. The old car hobby has been a source of income to me and my family for about 35 years; and has allowed me to build a business behind my home, and basically work from my home. The forums allow me to give something back to the hobby.
We vended for many years at the Iola swap meet, beginning with about the 3rd year. It was the favorite swap meet for us all, because of the friendliness of the Iola people. Hershey was better financially, but Iola was more enjoyable.
We stopped going to Iola when the legislators of Wisconsin, in what seems to me as moments of zero brain wave activity; redefined the term "commercial vehicle". To have continued to vend (legally) at Iola, we would have had to convert the motorhome to CDL specifications; and both my Father and myself would have had to acquired CDL licenses, logbooks, etc. It was not worth the effort. I understand the law was revoked after a few years, but we had already given our spaces to a Wisconsin company and did not go back.
Jon.
