It's a little after 3 AM here and this happened around 1 AM. I had woken up at 11pm(Went to bed around 8:30pm). Anyway While I was watching a movie on the computer, I heard something either bump or try and open the screen door but 2 of our 3 dogs started barking and whoever it was ran off. I went to look out the window but I didn't see anybody. The motion light was still on for a few more minutes before turning off. I'm pretty sure that if the dogs hadn't barked, that person would have gotten in somehow. I wouldn't have been surprised if they had as last year someone tried to stealed my bike at 6 AM while I was awake and the dogs didn't bark to let me know. Luckily at that time, our neighbor chased off the bike thief.
