We just built a 24x50 office carpet on road track down in Grants Pass to go next to our off-road. We have black carpet tracks an hour and two hours away.
What are you specifically wanting help with guiding the off roaders with? Happy to answer any questions. GT12R is super popular in Southern Oregon (Roseburg and Klamath Falls) Foam is a smaller following but getting pan cars into hands will slowly get people to run foam also.
