i like the track the way it is with the concrete islands etc as it takes a lot less time and is easier to set out a track
(track can be laid out easy by two people), having rostrum on other side is a good idea so is having it fully astrod, maybe have one cobbled corner or summat,itl be good if we could get some astro in large lengths to cut down on weeds and having problems with joints curling up or needing re seating with big hammer,but aswell the blank canvas idea will be less maintanence and proberly not generate as much interest with the kids in trashing it with bikes and so on!
