BASS presents our favorite event, kickball! We will be at our normal spot in the East Bay at Bushrod Park in Oakland! Bring your soccer cleats (for better grip on the field), sunscreen, and athletic wear and water for a fun time out! For those who haven't played kickball before, the rules will be explained and demonstrated before we start. Depending on the attendance, we'll either have 2 teams facing off or a rotation of 3 teams all together. Then after we may hit the local pizza/bar scene if everyone still wants to hang out. We have a HARD START at 1pm, so please be sure to show up on time for warmups! (We also nearly lost the field previously because not enough people were there on time) See you there soon! šŸ”“ Note: Please, please, please don’t no show. šŸ™ It makes these events really difficult to plan. If you no show once, you will be given lower priority for future events. The second time, you will be removed from the event list for any attendee limited event we host.
