Diving is diving if people only did it in the ocean the business wouldnt be half what it was now there are many lakes and rivers in the us with depths and great sites to see also when a hurricane hits the coast you can still dive...equipment lasts alot longer one spot we dive is a little over 100ft deep another 200ftlake was 10miles out in the gulf and it was only 101ft diving is diving..enjoy it while you can
