Eh, if they aren't trouble makers like Len, I see nothing wrong with it. Now I got my things I got tism about, we all do. But I kinda sometimes like knowing there are people out there like that because to you or I an elevator is just that, but when you step back and think how much is in them it's pretty amazing. I like how things work and these people are happy to share it. Much like to some a car is a car, if it's got 4 wheels it's good enough. To fans they know what cars are all wheel drive, rear wheel drive, and what they like and know. Hard core geeks will explain how their are different ways to do all wheel drive and brakes and yada yada, but if you aren't pure tismo, you can still break down and give people a 101. If elevators are you jam..by all mean, but I can see how it's a strange thing to link onto.
