You have to check out the extensive sets of photos and video tours and interviews from this year's Tucson Gem & Mineral Show, posted on The-Vug.com over the past couple of weeks.
There are links to other sites with reports and photos from the show. If you haven't been to TGMS, this site will give you a real flavor of what goes on. Now, the 45 independent shows going on all over the city are another story.
