I keep my bike inside. So totally safe there. When I go riding I never leave it out of sight if I stop for any reason. If I stop to purchase something like fuel or hydration I take it inside with me. If the store won't allow it, (most will where I am), I will move on to a store that will. If I have to leave it somewhere while I do something I always keep it in sight and it is "secured" with a light combo cable lock. The lock's purpose is simply to stop someone from grabbing the bike while I am standing or sitting nearby and then taking off. At 73 there isn't anything I could do to stop them as they sprinted or rode away. I remove my Garmin and lights too. They are an easy snap on and off.
