Taking the cold plunge

Most get into the cold cold water all at once (~70 degrees F....but its cold when the outside temp is in the 90s)
The run downriver takes about 20 minutes-ish, so you just keep going back to the springhead and swimming (or floating or snorkling) down. Stop for a picnic cooler snack , birthday cookout hamburger/hotdog or greasy fries from the one man owned forever concession stand.
