Four freshwater lenses occur in Bermuda , with the Central Lens being the largest on Main Island , containing an area of 7.2 km squared and a thickness greater than 10 m. 
 Can you tell me more about the local traditions? 
 Can you give me some insight into the culture in Bermuda? I'll be traveling to the area this winter and wanted to learn more about it before I go. 
 Do you have any additional information about the geography of the main island? 
 That's pretty casual. I love it! Are there any local festivals that happen annually?
