Michael,
The only N scale club I know of is out east of Orlando on Colonial Drive. Exact coordinates are 28.561857,-81.157874 on Google Maps. It's at Sherman Drive and Old Cheney Hwy. Zoom in to Street View and look southeast. Directions from downtown:
Take Colonial Drive (FL 50) east. When you pass the entrance to the toll Spessard L Holland Expressway (FL 408), you're getting close.
Watch for Avalon Park Blvd on the right, then a Kangaroo Express station. About 800 ft beyond the Kangaroo there's a mobile home park. The next right with a right turn exit lane is Sherman St. Turn on Sherman and go about 0.2 mi to the stop sign. The road jags to the right a bit, and the club is on the left beside that road, just beyond the stop sign. Look for a typical freight house style building with a crossbuck standing just right of center. The entrance is by the freight door at the far left end.
Only problem, I haven't been to Orlando for over eight years, so I don't know their schedule. They were a welcoming bunch the last time I was there. A member called Charlie adopted me and showed me all around.
I'm sure someone who knows when they meet will chime in.
