As in all over Mexico, no beer can be sold during election weekends. Some hotels will allow the tourist to drink beer on their premisses but if you are caught drinking beer on the streets, you can get into serious trouble.
Also beer or alcoholic beverages cant be sold until after 10am. So if you go to the liquor store, market or restaurant and you ask for a beer, they will say No, wait til 10am.
Because San Felipe is a "cash" society, Make sure that you carry enough cash. Alot of larger hotels do accept credit cards also alot of eatting establishments. But the little whole in the wall establishments (good food) accept only cash. Also if you want to buy some souveniers, bring cash.
San Felipe was founded in 1916 as a commercial fishing port. It still operates a sizeable shrimp-fishing fleet of small pangas.
The sea water is maintained as clean as possible because of the great dependence of the town on the fish and shrimp industries. Tests of the bay water in past years have revealed minimal detectable e-coli contamination. However, the further away you are from beachfront development, the cleaner the water will be. Because of the high salinity of the sea water, swimming and floating are almost effortless. Twice a month, around the time of the new and the full moon, very large tides develop and you will see the spectacular rise and fall of the water.
We went out with some of the locals, very early in the morning to go fishing. One thing i have found out is that fishing is not my thing! I had more fun just riding around on the boat.
When the tide goes out you will see many people looking for clams in the "mud". We actually found a few as well and you might see little tiny crabs. I think I mentioned it in another tip already but San Felipe is famous for it's tides. There is almost no other place where it goes out so far.
