I'm not sure how good this would be to attempt to post coin shows there. Note there are coin shows in most states and trying to post all of them could become a mess. Wouldn't it be easier to just make a link of some type to something like www.coinshows.com where there is already a listing of all the known coin shows in all states? Or possibly this calendar could list coin shows not shown on that sort of web site.
I have seen that website, and I have to disagree with you Carl. Personally, that site is not very helpful at all - it gives no details, no dates, no locations, no times, and usually not even a link to the information about a particular show. All it provides is the name of the show and "fall" or "spring." I won't even bookmark that page.
