Some online riders were kicking around a campout around Julian / Borrego Springs perhaps in Late Jan to Early Feb. The wife and I have wanted to take a winter campout. The locals would likely tent....
I've stayed at Butterfield Ranch a few times for a dual sport ride in February and it works out great. Older park that is being refurbished. Management was nice. Right in the state park. Haven't been there in a couple years but planning on 2016
