Medellin, Cartagena, Bogota

I'm a 73 year old US expat living in Coatepec, Mexico who has booked a trip covering these 3 cities
I'll be spending 2-3 days in each of city in mid May.
I have hotels and sightseeing booked.
The last day in each city will be unscheduled and I'd appreciate any inside tips on unusual places to see and things to do.  I'd also enjoy meeting expats and Colombians if anyone is interested.  Please Private Message me if you'd like to meet up.

Regards,
Barry

Hi Barry,
I am British and live in Bogota and happy to meet up.  If you tell me where you are sightseeing in Bogota I could suggest some other places not so well visited.
