Actually the new vibe is the old vibe. I don't remember exactly when the PWC appeared but remember I first noticed the noise & the smell. The hustle came later, at least from the aggressive salesmen. Not all are.
It's something many tourists want. That's why they're there. It's part of tourism on the water. Think FL & other states w/ water borders, lakes. Regulation & education is needed. I feel for those who have lost their livlihood as well as the investment in the PWC.
