Pax rode in the sidecar of his dad's new "Ural Tourist," which is Brad's new toy that he most likely got over the holidays.
The father and son duo hit up the local Gelson's grocery store, located in the hipster Los Feliz area in Los Angeles.
Pax was later seen coming out of the store holding a fistful of cash in one hand and a grocery bag in another while Brad held on to their helmets.
Seems like they were picking up some last-minute items before ringing in the new year on Saturday.
Pax is one lucky kid! We bet all his sisters and brothers were fighting over that sidecar spot. LOLz! Both he and dad looked seriously too awesome while riding it around town.
