Chuck<br>I don't believe it is fair to characterize this as a hobby just because you choose to do it without payment. Fortunately, there are folks, like yourself, who provide service and expertise without requiring payment. When it comes to travel expense, that seems to be asking a lot. I think the answer is that some people do have jobs that pay their travel for volunteer work. I know some of them, but I have not had a job like that. Good luck with your work, paid, volunteer, as hobby or even for therapy.<br>
