Howdy Kyler or whatever you're going by
(Tim, maybe?), for I tried getting some response on this issue, but so far haven't come up with anything, as yet. As I re-read your message, I see that it was your brother inquring about the Southern California Grotto, so sometimes getting the information straight could be mind-boggling. Anyway about it, as for caves in the Southern California area, your brother is correct that there's not too many caves around there; thus, the cavers have to travel somewhat to go caving, like to Sequoia National Park and farther north, but this has been going on for years and years. A lot of grottos are in that same category. We've been in communication with a gal who lives almost up into Canada and caves down in TAG country, so...what your brother got--information-wise--is nothing new if they're into caving.
I was pushing you into getting into this grotto, so that you could know somewhat was expected of you on going on trips, getting their great newsletter, and maybe joining up on some of their training, for let's face it, grotto folks usually like to know who they go caving with, whether they're safe cavers, etc., etc. If I can find other info out for you, I'll probably do a PM to you.
Guess it's not you who would be joining up with Southern Cal Grotto, but your brother, 'eh?
