With the temperature getting hotter be sure to carry plenty of water. Hiking along a stream makes it even better. You can dip a towel in the stream to cold off. The SAWMILL is one of my favorites because it's a main connector for traveling three sections of the Patapsco. Always enjoy the boulder hopping and cascading water along the SAWMILL. You can also sit on top of the TRAIN TUNNEL when you hike the DRUGS trail. It's a steep trail so I recommend always go Down it.
