Finally, the spring season is here, and my family and I have begun planning a road trip for this summer. One of the places we would like to visit is the Yellowstone National Park and we are set on seeing the Old Faithful geyser eruptions. To witness this natural wonder, we could plan to stay at the park for half a day or we could use data to our advantage to plan a much shorter wait time to see the geyser erupt over 100 feet. What tool from the quality tool kit would come in handy to minimize our wait while maximizing the odds of seeing a long duration eruption?
