The Raffle
The crowd favorite of the SevenStock event is back and just as great as ever! This activity is a great way to expose your products to thousands of event goers and show your public support for SevenStock. As in years past, we are soliciting the donation of Rotary related items/products from all vendors in attendance. Donations are strongly encouraged, yet are not required for you to participate. Your assistance greatly helps the SoCal RX Club offset the cost of this unique not-for-profit event. We continue to extend our appreciation and thank all of the vendors who have donated items to past years’ events. We look forward to working with you all again! Proper and generous promotion of all vendors and donations will continue on all of our web and social media outlets.
