I was just looking at the same info myself Rick. I also have a USFS San Bernardino forest map but it does not show the T-6 crossing itself. I think I remember a conversation with Greg Hoffman who is the USFS OHV enforcement person and he indicated to me that the T-6 crossing is the bridge crossing Deep Creek. I tried calling him today but he was unavailable and the USFS was not available on Sunday at the phone number I have for them. I'm going to look further into the USFS website to see if they have more specific information on exactly where the T-6 crossing is.
