Mass start at 10AM is optional. Registration at Active.com or Potosi Brewery web site or Facebook Event.
Also included for no additional fee is live music, and a huge lunch served with Potosi Beer or Potosa Root Beer at Holiday Gardens. It is really a great party. You will start and end at Holiday Gardens, across from the Brewery.
The route is River Lane along the Mississippi Flyway – so you are likely to see some birds of interest around the marsh and wetlands there.
