Miss C, it wasn't until you mentioned that that I realized how unusual that warning might be. I was born in Miami (where Dave Barry worked for the Miami Hearld) and lived in Leon County. I can't count the number of times I saw an alligator - most often in parks and wildlife areas, but also in the city, and tourist place like Silver Springs. Last time I was in Leon County we went for a walk in the St. Mark's Wildlife Refuge. The scores of gators weren't scary ... until sunset when they started moving.
