If your dogs start barking on the way to or from Lollapalooza this weekend, hop on the trolley sponsored by artist-designed footwear brand BucketFeet and technology accessory makers Lunatik. Besides a lift, you get free swag, giveaways, cold water, and a preview of the limited-edition BucketFeet "Skullz" design. It runs from noon to 3 PM Friday and Saturday around the festival. Follow @BucketFeet on Twitter for location updates.
