I didn't think I would need a lock today. I planned to ride and return home. But the more I rode, the more I realized I needed a new saddle. I went to the bike shop which was fine since I took it inside. But I rode longer and could have used a smoothie but didn't have a lock. I struggled to make it home. I am going to put some cable locks around my seat posts. At least I will have on if I need it.
