@Jerry K.Thanks for sharing. invest in raw land has so much opportunities if you know what to look for the different components, like soil, vegetation , mineral rights, water source...etc.In your case is the billboard.

They had concerns about liability, possible spreading to vegetation, trees or adjoining properties and air pollution from general burning and burning of toxic substances such as lead, asbestos, etc. 

Over long periods of time vapor itself can leave a thin Vegetable Glycerine (VG) residue that is easily removed with a warm wet cloth.

I have not checked into it yet, but I believe the city declared it unsafe to enter because vegetation has grown up all around the entrances.

Another possible use I've seen here is a community vegetable garden, which is a good concept, but doesn't generate any cash flow.

If the property has trees or heavy vegetation roots growing into the pipe can clog it.

One note- you wont get new grass to grow in it,,,neither will you get a vegetable garden to grow for a few years afterward. 2, 4, -D is the least dangerous,,, cost effective way and safer to trees if not sprayed directly on them.

If a family on foodstamps can only afford to eat boiled rice with margerine, their kids are not going to be as healthy as mine, who eats baked boneless skinless chicken breast, steamed vegetable, and a nice green salad with fresh fruit for desert.

Things have been good as long as she stays away from raw fruit or raw vegetables.

Also have some space where people can come and plant their own vegetables in return for volunteer time on the farm.The world needs this a lot more than more houses and storage units...
