On Sunday, Griswell juggled in Peace Park. "I was going to ride my motorcycle today but the battery was dead so I decided to come here and joggle. The warm weather is going to be brief so I just want to make the best of it," he said. According to Griswell, he started juggling 10 years ago while living with two professional jugglers in San Francisco.
