The the "only 20 minutes" sign
and the dude with the gas mask
were an interesting discovery when we got to the peak. Then peering into crater we saw all the gases leaving the earth. It was pretty cool, but I don't think my pneumonia-damaged lungs appreciated my hike to this poisonous place. Oh well. 
For a little more history on this place, I can tell you it's only been active since 2001, but the last eruption was 1856. It's one of Costa Rica's biggest volcanoes.
