Nope, not unless you plan on staying over 90 days. But you will need a passport!
Do you know Jacob? Do you think he would want to live somewhere safe??? JK:) Don't walk down any dark alleys and don't be flashing your cash around. You should be fine.
Hmm.. better safe than sorry! But, Colombia’s major cities are known for the high quality of their tap water, so don’t be afraid to enjoy some juice or a drink on the rocks. However, as is the case in most South American countries, consuming tap water in the countryside can be a bit of a gamble. If you're planning on going off the beaten path, chat with a local expert about the water situation before you drink up.
You should not be concerned about using your credit card in Colombia but let your CC company know you are leaving the country or they may turn it off on you!
The tropical weather is warm to hot all year. September has a high of 89, low of 78.
No, but it has helped Jeff. His extensive vocabulary consists of 'cerveza' for himself and 'bano' for Lori. We have done just fine:)
