Riding anywhere along the Newport Beach - Huntington Beach bike paths requires peace, love and understanding. I was on the HB path this morning, and a kid was coming towards me on his beach cruiser, head down in his cell phone, texting away. I gave him a WIDE berth, and a "please look up". He looked up just as I passed him, absolutely amazed that there was anybody else around him.
Just keep it slow, watch everyone around you, and assume that they're oblivious ('cuz they probably are).
