Steve, you were asking about Mall Shows. I'm not exactly sure if you meant train shows or modular clubs based at malls. But as far as train shows goes, there are few good ones several times a year.
There are usually one or two large ones at the Puyallup fair grounds. The Great Train Expo will be Dec 15-16.
Boeing Employee's Model RR club hosts in in Kent in November.
Tacoma NW Modelers just had a show on May 14th at Freighthouse square in Tacoma.
Yard Birds Mall in Chehalis has a couple shows each year. The Olympia Lions had a show in March and the Chehalis group will probably have one in October.
