I found this description from the hosts:
"- Asha SF presents Holi 2014!
- Join us in celebrating the Indian festival of colors with our annual color fight! Asha San Francisco presents the event you've all been waiting for: Holi 2014!
On Sunday, March 30, from 12 pm to 3pm! How does it work?
Grab handfuls of different colors, and smear all over nearest face (self included)! Try aiming for friends or family, though complete strangers on the field wouldn't mind either. UNLIMITED COLOR is included in the ticket price.
What better way to welcome spring than by dousing friends with color, enjoying performances, and dancing the day away with a live DJ! We'll also have some of San Francisco's most delicious Indian food trucks - you will need all that energy to go back on the color battleground!
Tickets are sold ONLINE ONLY (no sales at the door)
*Early bird prices for the first 200 tickets!*
Early Bird: $15, General: $20
Who are we?
Asha SF is a non-profit, zero-overhead organization with the goal of providing basic education to the underprivileged children in India and all proceeds from this event will go directly towards achieving that goal. Come celebrate with us and be a part of this goal by participating in this great outdoor party!
