I would like to add another observation on this topic that deserves attention.
Last saturday I was at ocean beach walking between lincoln and vfw's and noticed quite a few people riding on twintips. I saw at least 2 kiters riding on the way inside bringing or maintainig their kite very low, immediately above large numbers of beachgoers. One into particular got alot of attention. While I am relatively new to kiting at OB my decades of surfing experience here tells me that this will get noticed, even without and incident/injury, by the beach patrol guys and safety-minded beach goers, especially with children (this includes me).
Perhaps some regular kite surfers can provide feedback accordingly.
