Today we ventured into the north entrance of Yellowstone so the kids could complete their Junior Ranging workbooks and to play in the Boiling River. The river is very cold, but right near this point there is a large hot spring that flows into the river. People have constructed little pools where the waters mingle to create a really nice experience. You can find the right spot that is a good temperature and current and hang out there. Sometimes you still get a hot or cold wave that passes you by.
