All of you enthusiasts egging Richard into the tour business should sit down with a cup of coffee and talk to Skip Moscorro of Motodiscovery. It looks all romantic from the outside looking in. There is much more than meets the eye.....the administration end of it is huge. Skip's wife Nancy holds up that end of the business model like a rock star, but she works her rear end off.
Skip is the pioneer, he's been going to Mexico since the early 80s and now, around the world. But he himself will tell you how much work he puts into it. The crux of the issue is, do you want to balance organizing these rides and riding them too, or cross the Rubicon into the full time tour business, where you'll find youself tied to the computer, phone, website, and file cabinet to make the business function and make a profit. Then, to go into the field, you'd have to have your wife or a hired gun run the phones while you go out into the field to have your own riding fix.
I'm not saying it can't be done, or that you can't do it and have fun and/or make money. I am saying that anyone thinking about following this path should take stock of the dues paid by those who currently make their living in this field.
