There is a Pack Beach Day outing on Saturday August 14th, 2010 at Bolsa Chica State Beach. I believe the cost is $15 per car. Check the Pack 29 website for the announcement or click here: Bolsa Chica Beach Day
You can also view the entire year of events (one that I know of that is) at the Calendar section of the Pack website - 2010 Pack Calendar.
See ya at the beach.
