Welcome to Minnesota S. - especially welcome to the "burbs" south of the river. I wouldn't put in a security system, but then I emigrated from Africa so Minnesota is as safe as heaven as far as I am concerned! We use our sprinkler system throughout the summer - couldn't do without that. This summer was so dry that the people in our neighbourhood who didn't have sprinkler systems and didn't like running out to move the hose all the time, actually had a lot of their grass die. If I had to choose between the two - sprinkler versus security - I would definitely choose the sprinkler. Good Luck with your move.
