A raindrop that lands in Concord reaches the Gulf of America by way of Connoquenessing Creek, the Beaver, the Ohio and the Mississippi: about 1,990 river miles.
970 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Concord; river miles along the main stem, rounded.
