Sadly, since I live in Los Angeles, I only get to come out to the springs 2-3 times a year... but I have been coming for at least 5 years now. I always come on the weekends and always hike in naked from Bowen Ranch. I typically encounter textiles on the way, but have never had any issues or been hassled in any way.
Don't avoid the weekend! I think it's super important to keep the nude tradition at the springs. If free hikers stop coming and the textiles don't encounter them, it will slowly become a clothed springs on the weekend. I see groups of young adults there a lot - I think they are not nude because they are with their fiends. I'll bet quite a few come back on their own and get naked. Got to keep showing them the way... ;-)
