If you get a chance to go for a good bike ride, consider the Blackstone River Bike Path. It runs from Woonsocket down into Central Falls. It can be accessed from the northbound rest area on i295 just north of RT 146 and several other points along the way.
This photo shows the low water approaching the Pittman dam at the 8.5 mile post.
