Smoking and obesity are the biggest contibuters to my business.

I have always had a huge interest in real estate and knew from my late teens and into college that I wanted to build a rental property business as a second job and eventually move to full time when I was able to.

We love Teen Titans Go!

It's easy to find a company or even some local teens to walk and put door hangers on every single home in the neighborhood.

He worked me like a dog through my teens.

@Eric BowlinThanks for the input.Some of the reasons you mentioned are the reason I use it now as a supplement.Normally, there would be a dozen of two of 8.5"x11" pieces of paper with detailed information, floor plan and inside photos, as well as web address for additional photo, my phone number, email etc...all on one single page.The problem is when that runs out...I put the box up first day all the papers are gone, probably from nosy neighbors walking by, so the QR code is a backup, it's better than an empty box.Obviously it's only for those who drives by, those who found the place on the web already have the web address and relevant information.As far as popularity goes, I guess my experience is a bit different.A recent quick survey I did at a party and a picnic, most of the younger kids, by that I mean teens and in the twenties have QR code reader apps on their phones, there is no need to download an app. 

Average lows have been below zero every night with highs lucky to be in the teens.

Peak lunch, dinner periods could mean parking issues, late night operations of lottering, teens at a burger joint could mean vandalism issues as well.

I evicted two obese lesbians the day after Christmas one year.
