Waterfalls and hiking are two popular pastimes along the Blue Ridge Parkway and the roughly two and a quarter mile trek to the 70' Crabtree Falls within the Crabtree Meadows Recreation Area is one of the more popular ones. The hike is slightly strenuous - it's downhill to get there which means it's all uphill to get back - but the view, like my photo above, is worth it.
...and here's why. You will find White, Red, Yellow and Violet colored fire hydrants pretty much everywhere. But there's a reason for this - and it's because of the National Fire Protection Association (NFPA). This association has issued guidelines for color coding standards for fire hydrants. These color codes from the body of the hydrant, top of the hydrant, and in some municipalities the outlet caps are designed to allow fire fighters to know what type of system, water flow rate (Gallons Per Minute or GPM), and level of water pressure. This guideline is known as NFPA 291 and is intended to be used universally throughout the United States. The NFPA guidelines are specific to the body and the top cap of the hydrant. If a hydrant is WHITE or YELLOW - it means that it is connected to a public/municipal water system. If a hydrant is RED - the hydrant is connected to a private system, typically a well. These are most common in rural or unincorporated areas
