The Frugal Traveler blogs about Colombia and more specifically the region (Santander) Nicholas is from and his hometown! They even mention the hormigas culonas- the rather dry and hard to swallow ants that I was so graciously given by his uncle on my first trip. We have done the long bus ride from Bogota to San Gil. I have done the whitewater rafting twice and the rappelling they mention. As well as tasted the pepitoria. And, as the recent tourism campaign goes (ad after NYT video): The only risk is wanting to stay!
Read the blog and when anyone wants to make a trip to this beautiful land, you have two very willing tour guides at your service! Check out the video, there is a close up of the ants, yum!
