Something we see on most of our visits to Tamarindo: most nights there are bands of fire dancers who go from one beachfront restaurant to another, performing for tips. It can be spectacular and I think they do pretty well. Appropriate, given the risk of losing their hair, ears, etc. There are a bunch of these images and I may post more.
Disclaimer: the video display on my laptop seems to be failing and I can't guarantee the accuracy of the color on this and further images until I fix or replace the machine.
