Here is an article from the business courier that talks about a couple of the developments coming soon. http://www.bizjournals.com/cincinnati/news/2016/07/08/11m-mixed-use-project-coming-to-this-cincinnati.html

A tenant photographed another tenant holding a vaporizer in one hand while hiding out behind the building.

I wouldn't hide the felony.

Guns are pretty easy to hide. 

Oil-based works well (fumes are another story), but I have yet to find a stain that the water-based/latex Kilz actually covers/hides.

Home Depot's selection is extremely limited and costs the same or more for worse material, whereas if you find a roofing supply house in your area your options open up wide and you'll get a reasonable price (and as all cash mentioned, they'll give you rooftop delivery for a reasonable price which is absolutely worth it).Architectural shingles are nice because they're good at hiding minor imperfections.

During the inspection, I discovered that the drop ceiling was also hiding two can lights and new [minor] leaks.  

Possibly painted neutral or green to match the house; or (not that I would want to add more to the already small yard) hide it with something.  

You have nothing to hide if you are doing business properly.

If you are attempting to hide or conceal something from others you should probably not use your own name.
