There's always a negative opinion on everything. I'm looking for operating tips, troubleshooting tips. The future of DCS. Last year had very good troubleshooting tips and how to test signal strength on your layout with a AM radio. Atlas O was there giving there input and future with DCS in locomotive lineup. Plus the camaraderie of DCS users and meeting new people and sharing ideas and stories. If it does not interest you, perhaps don't go.
