I got a parking spot 2 rows directly across from the front door of Orange Hall.
I had a nice conversation with Mike Wolfe about HO trains, spoke to the Biancos at length about things in the hobby (they are a forum sponsor via Train Land/Train World), Enjoyed chatting with Paul and Marcia Johnson (owners of Catoctin Mountain Trains and Hobbies in Thurmont, MD), and was floored when the folks at Bachmann asked me what I thought about the blue tooth product they now have and they seemed interested in my opinions. And I brought a 'guest' to the show - a friend I have known for about 43 years.
I know that is not specific train stuff I brought home (did get a few items), but the above are the things of most value to me.
