My friends and I are also into bicycling and we are also thinking of trying out Montevideo. We are all girls,and we are like a group of six. Is it safe to go cycling there even if we are all girls? i really hope so. We are all dying to go there. In fact one of my girl friends bought six exact the same helmets for uniformity. CAn't wait! I know it's going to be a lot of fun.
