Not a question of being afraid.
This morning I sat in my car, windows open, light on reading a book while listening to some good blues.....at 5:30!! Not a worry in the world.
Listen there are some stereotypes here and one of them is that US teens do drugs. So the local drug cops could well target a nice big kid with a drug snare. The real drug dealers also have the same stereotype in their minds.
Now, I have to admit that I have not been to that beach is years and years, but I sort of doubt that there are throngs of drug dealers offering narcotics to everyone they see, as if they were peddling seashell trinkets...
I'd tell the kid to be aware of the stereotype; to be totally confident in telling anyone that even implies something illegal or irregular to go and f*ck off!!
Look, this is a really laid back place where kids drink and dance until the dawn, but generally speaking, they do it without drugs (except the alcohol...)...
I would not hesitate to have fun yourself, and let the guy roam...We raised 11 and we did not have problems with this issue.
