The next time you head down your favorite trail be sure you have ParkWatchReport downloaded on your smart phone. Open your park's page to find maps and check for alerts. Then, if you spot something significant, File a Report. Your Report goes directly to that specific park's management for action.
The free phone app is available at Apple Store and Google Play. The same features, including File a Report, are available on the ParkWatchReport website at https://parkwatchreport.com
