We have been hit again

Sadly, we were broken into again in the middle of the night. This time they came into our garage and stole Sara's $5000 mountain bike and her shoes that clip into the bike. So it's someone who obviously knows bikes because I would have no clue on the value of her bike and shoes. We woke up with the garage door open and only those items were taken or so we think. We might not be remembering something else because who keeps tabs on all items in your garage, I mean really. But tons of other items of value were untouched oddly. So that leaves us wondering...is this the act of the same thieves that took everything in Chris's truck who got the garage door frequency or is this a solo act by someone else? We are left wondering and worrying about our safety. We have a motion detector now in the garage that alarms the house. We also unplug the garage door so it can't be opened at night until we plug it in in the morning. We now have weapons in the room and a hammer hidden in the laundry room. We park both cars in the garage every night for precaution. All this after 2 burglaries in 2 weeks. Sad and scary.
