TMC Connect is a (mostly) annual conference put on by Tesla Motors Club. A great way to meet other people from the forums in person, as well as some Tesla owners who don't frequent the forums much (see post #5 above). Lots of speakers on topics related to (duh) Teslas, other electric vehicles, clean energy, etc. You can click on "Conference" on the top bar of the TMC pages to see more photos, etc. of past TMC Connect conferences.
