Volcanoes Stink

We visited Volcanoes National @arks today and it stunk - litterally. The sulfer dioxide levels were at a dangerously high and many trails were closed.We decided to grab some lunch at the Volcano House which overlooked the crater. During lunch we remembered a trail we had seen along the road on the way up and thought it might be far enough away from the crater to hike safely. After driving for about five miles, we parked, put on our hiking boots, arranged our packs and hit the trail. About 100' into the hike a sign straddled the path declaring the trail closed due to dangerous levels of gas.Did that stop us - heck yes.
