They say good things come to those who wait and that is exactly what we are having to do at the moment. And while we don’t (seriously) propose waiting 50 years to see a geyser erupt – quite literally: the Steamboat Geyser in Yellowstone National Park lay dormant from 1911 to 1961 without so much as a steaming burp – when it comes to the Great Fountain Geyser, your patience will more than likely be rewarded.
