Me and my family have camped extensively in and around forest road 376 in the Jemez mountains over the years. It is a truly beatiful area. It does get very crowded on any summer weekend. I imagine it will be even more crowded with these new restrictions. Most of the best sites are easily more than 150 ft from the road. Shame. Hope this ruling gets overturned.
I also used a headphone patch cable that connects TV headphone jack to the radio aux input. Works great. I can even switch speakers from front or rear or both. This solves problem very inexpensively. Good luck.
