I'm not sure about that....Last weekend I noticed broken curbs on two sides of the roundabout from some hard hits, a very nasty set of skid marks that went over the curb and into the grass towards Meredith and another set that went through the middle of the roundabout.
I saw a few close calls with Motorcycles last summer so FLL you should be careful riding your bike in the rotary after your daily trip to McDonalds.
