I have been to the Grayslake show a couple of times, since its only 12 miles from my house, which is an easier drive than DuPage, especially in bad weather. Its in a new building that is a bit larger than the main building at DuPage, more like the new building at Kane County, and it is oriented toward families and newbies.....nothing wrong with that. As stated, not as much O Gauge as DuPage, but enough to keep me interested. I'll go, just to support it...I don't buy much these days, but its always nice to see whats going on. I only get down to Wheaton once or twice a year, even in great weather.
