But if you are a senior investor, I can see being on a glide path to fewer properties and maybe no debt. 

Also, if you're on the road Driving for Dollars and getting properties, you should consider using the Land Glide app.

It is a lot cheaper to do non-emergency repairs....Provide floor glides for furniture on move in  so your tenants don't  put giant scratches in wood floors.

I'm a hang gliding pilot and aspiring paraglider pilot. 

So, baring a court case or clearly articulated set of policies, you may run into pushback from cities or you may glide through (for now).Now, to put my City hat on (I do development, advise developers and handle the City's real estate portfolio) the biggest obstacle is zoning laws.  

Some of the drawer hardware can be replaced as the same companies still make 1970’s style glides.

I used to go hang-gliding in Hickory (early 80s)--Lenoir, actually.

You can buy new drawer boxes too, but new drawer glides are what makes them feel new.

As far as outdoors go, you can hike, swim, fish, kayak, glide, camp, and so much more.

look inside one of the existing drawers to see if there is a company name, so you can call and order the drawer and glides.
