That sucks. FYI- the best time to rob people is during the day, when they are at work. The neighbors are likely at work too. Pull up in a van with some plumber logo on the side, and you can load up all the goods of the house within ten minutes, in and out. Ever watch that TV show, "How to Catch a Thief?" That is how they do it.
Good tips, slow down the thieves by using good locks. (remember that locks are made for honest people and thieves will go right through them, but at least you can try and slow them down.) Also, on more expensive items like a nice chainsaw, buy a Dremel tool (they are rather cheap) and etch your name and phone number or email address into the items. One should be very visible, and etch it again in a less conspicuous place so that the thief doesn't file it off. You can also use the luggage technique of spray painting your luggage a bright ugly color, so that it is easily recognizable and not desired by others. -- Do the same to your chainsaw, lawnmower, etc. Make them ugly. Installing a few mini-cameras is also a viable solution to catching the thieves. These days, you can even buy systems which are motion-activated, and will send you an email of the video, immediately, every time the motion sensor is activated. Then, you can call 911 and give them a description of the person and/or auto with license plates, and inform them of the crime in process, so that the cops can go bust them.
