I keep looking at the 0 and 027, mainly cuz it's the same as what we had as kids! Nothing is a good match for scale (maybe G) but I think I can go with the mis-match on scale for the nostalgic value! Probably still have some Lionel stuff around someplace out at Grandpa's house. Heck, it's going to be to have fun with so I doubt if I'll be getting a lot of the hi-dollar goodies unless the girls still have an interest in it when they get a bit older. Gotta do something, still a few years till the girls are old enough for Jr. Dragsters!
