Re: discussion on fire roads in Socal:
Don't worry, there are more than enough fire roads left in Socal to access things like telecommunication towers, powerlines, trails, and other infrastructure. For obvious reasons these get maintained. Fire access is still a major reason as well and is why I always thought they were called fire roads. Truck trail is also common. Forest road is more often used on National Forest lands. Plenty of them are not maintained with cost being a big factor. Roads are expensive to maintain and if they can change the designation to non-motorized trail then they don't have to maintain it regularly. Lots of roads in the Angeles NF like Cucamonga and San Sevaine Truck Trails are a constant battle against mother nature with frequent rock fall and washouts. The roads can easily get wiped off the mountain if you get big storms following wildfires. Lots of them have been closed to motor vehicles as part of forest management travel plans. Thinking of Santa Anas in Cleveland National Forest, Harding Truck Trail is an example that is no longer open to vehicles and is generally not maintained. It goes back to singletrack if enough years pass between fires. Every time there is a fire though, it gets bladed back to drivable road, so there is still legitimate use for fire access.
Environmental groups also push to have roads shut down to vehicles. If they can get the designation changed from motorized to non-motorized they can call it a roadless area, and push for Wilderness designation. This is exactly what has been happening recently on BLM lands in Moab and San Rafael. First kick the OHVs off, then kick the mountain bikers off with a Wilderness designation. Land managers are too happy to go along with closures not just for cost savings but also because they don't want to deal with the headache that access creates, especially near populated areas. Just look at the account Maple Springs Can't Drive for some great examples. They are quick to close gates when a storm or Santa Ana event is coming, and they take their time to reopen them. At least we can often access them by bike, but the closures following wildfires keep getting longer and longer.
