The area around Spring Mountain gets regular patrol of Police Officers on Dirt Bikes and Council Officers handing out up to $700 fines. Friends who regularly go trail bike riding in that area have said that there's no chance of "doing a runner" as they said, as huge nets get set up to stop bike riders doing precicely that. I've been given a written warning once already with my rego details being recorded. I don't think they give warnings anymore though...
It's a shame really that we can't use the area now as in a few years it'll all be shopping centres and carparks anyway...
I know families who have been taking their kids there on the weekends with their pee-wees for a bit of fun for many years. It's the greater Ipswich areas playground. People have "grown up" in that bushland area an it's all going to disappear now!
