Glad you are taking appropriate precautions dgolds.
Since I've never been, I can't advise you but my friends wife is a native of Bogota. I'll try to find out what I can from her and let you know. She has always recommended extreme caution. Recently, the government plan making everyone including rich executive types take public transportation to help alleviate the traffic nightmares lead to a huge increase of mugggings on buses, etc!
And you've heard I'm sure,"they" (rebel cheiftain) have declared war on the US!

BTW- He, her husband, has never been down there. The family, etc comes up here. I do hope things improve quickly down there!
