Moveable Raised Bed?
Anyone have ideas on making a moveable raised bed for me to expand my 'garden' onto the conrete driveway? The thought of a flat bed trailer has come to mind which would have the heft needed to support a large amount of soil, etc. but I would like something the kids could move if they wanted to shoot hoops. It would also double as a potted plan storage platform in the winter, pulling it into the garage at night and out into the sun on nice days.
Thoughts would be appreciated.
