Lake Boca seems to be on the inter-coastal. I've seen a lot of boats congregate on Sundays and lounge around. But my question is.....Is kitesurfing allowed here?

here is the link.....

Also, someone mentioned in another thread that it is unsafe to swim in inlets because of sharks....Is that true?????
