Resurgence of old dirt bikes?

I have seen and answered a lot of questions about motorcycles from the 70's and 80's and it's a good thing that people are taking an interest in them. When I rode a lot in the 90's, everyone thought they were dorky or pieces of crap. I rode them at the time because they were cheap or free and thats good for a poor teenager to have fun on. I have had a 73 Yamaha SC500, a 72 Yamaha RT 1, a 79 Yamaha IT175, a 78 Honda CR250 Elsinore, a 73 Husqvarna 250 WR, and now an 85 Husqvarna 250 XC. So what type of old dirt bikes do you have?
