Salento is a cool, small town, set in the mountains which are thickly and colorfully covered in tropical forest and surrounded by coffee farms.
The locals wear big cowboy hats, very short ponchos and hang metre-long knives on their belts. Most are big fans of General Wellington's boots. It is also the first town where moustaches are frequent, bushy and awesome. Possibly due to the rubber booots, they all have that slow John Wayne walk, throwing each leg forward and then letting it flop down.
That, the actual cowboy attitude, look and eyes, the small town feeling, the horses galloping down the square, the colonial church around which the city is built, the number of pool houses and saloon-like bars all add up to give the town a "tropical western" sort of feeling.
You could easily imagine Clint Eastwood riding into town with a single bullet in his colt, speaking in dubbed Spanish.
In short, we and I like Salento very much. The fact that the locals grow their coffee and their moustache goes a long way towards this, admittedly, but the Old West atmosphere is a great and unexpected bonus.
