Bordering On Danger

As I am learning on this trip, the perception is not the same as the reality, however, anyone considering a trip to Colombia should be aware of a few common sense tips.
Avoid the border areas with Panama, Venezuela and Ecuador. This is where the bad guys hang out in the mountainous, heavily forested jungle areas. Driving a car on your own is really not recommended.
Sticking to the main cities is the best bet. Bogota, Medellin, Cali, Cartagena all are quite safe, but take precautions as you would in any foreign city.
Organize any local tours and arrange for taxis from your hotel concierge.
Keep a low profile as an American. Dress appropriately. Aside from clubs and bars at night, Colombians dress conservatively.
Don't flaunt your jewelry, watches, or money.
Respect the fact that this is a country that has different politics and customs than ours.
