I'm currently a "rug" racer - meaning that I don't have a permanent track. This is because of lack of space. My house here in England does not have a garage, game room or anything alike. So for time being the track gets built in the lounge and dining room.
I love technical tracks and Scalextric allows for that because of the variety of track pieces. I also like to race fast between 2 or 3 bits of technical track, so you will almost certainly see 2 longish straights in my tracks.
