Regarding your Pipa photos, this comes from the virtualtourist site:

"Be sure to experience Pipa at night- after 9:00p.m. Like many places in Brazil, it looks and feels different at night. During the daytime it can feel a bit deserted, but at night everyone comes out. There are many restaurants and bars in Pipa- you won't be wanting for a place to eat."
