A neat trick: if you are using Google calendar, you can go to the left, scroll down to "Other Calendars". Click the "+" sign, then "from URL", then scroll down to "Integrate Calendar" and enter the following gobbledygook (all one line, cut and paste is best):

https://calendar.google.com/calendar/embed?src=board%40desertdolphins.org&ctz=America%2FPhoenix

Then. all the Desert Dolphins activities will automatically appear on your calendar!
