We added a new section on Astronomy and Heavens . You can find them under the camping skills. Included is a complete section of star charts for the Northern Hemisphere. We are working to find something for the Southern Hemisphere. If you have any leads, please contact us.
We also added more information on the dangers of Rip Currents and how to escape them. I never realized but Rip Currents account for 80% of rescues at beaches and over 100 people drown each year from them as apposed to only 18 from hurricanes in the US. See the stats here.
