Read the rules that I posted, they pretty much cover everything that is out in our local waters. You can go to many different areas to harvest but the collection limits have dropped significantly. It's harder to justify the expense of driving down there.
Ricordia for example is down to 5 per day. If you stay somewhere for more than a few days it may be worth the trip. Keep in mind that if your are stopped leaving the Keys (or anywhere else) with more than one days worth of livestock, you need to be able to prove that you stayed for multiple days.
There is a difference between surviving and thriving.
