The annual Sn3 Symposium is kind of an odd creature. It is a fantastic annual event focused around Sn3 modeling, but there is no overseeing organization that puts it on every year. It is organized quite organically by a group of local modelers that propose to hold a particular year's Symposium in their town.
An Sn3 Symposium is quite similar to the NMRA or NASG Conventions. It is held for several days, offers how-to clinics, contests, vendors, local layout tours, etc., and provides a place for modelers from all over North America (and even abroad) to gather and share ideas. The "Sn3" part in the title should be taken lightly, because you will find other scales' narrow-gauge layouts and modelers at an Sn3 Symposium. So, it really turns into more of a pure modeling-focused mini-National Narrow Gauge Convention.
The NASG is not directly involved with Sn3 Symposiums, but we still wanted to have a page dedicated to this annual event. If you are interested in Sn3, bookmark this page, so that you can always find the latest.
