A deployable mobile trailer with multiple deployable walls is disclosed. The mobile trailer includes wheels rotatably coupled to a base and a frame attached to the base. The frame has vertical supports attached to the base and a top frame assembly disposed at a top end of the vertical supports. First and second elongate deployable walls are rotatably attached to respective first and second sides of the frame. The first and second walls include and are movable between respective retracted and deployed positions. A deployable end wall is rotatably attached to an end of the frame and has a retracted position and a deployed position between which it is movable. Multiple activity devices are removably attached to the top frame assembly, the first elongate deployable wall, the second elongate deployable wall, or the deployable end wall. A mobile activity structure and method for operating a mobile deployable activity structure are also provided.

Systems, apparatus and methods for recovering golf balls from a surface at the bottom of a body of water are described. The systems and apparatus comprise a picking assembly configured to pick golf balls from a surface when moved along the surface and a docking module configured to receive the picking assembly and to remove the golf balls therefrom. By repeatedly dragging the picking assembly across the surface between progressively changing points on either side of the surface, it is possible to recover golf balls from the entire surface.

Embodiments of the invention provide for a mobile bungy jump apparatus which comprises a wheeled vehicle, e.g. truck, and a jump-off platform carried by the wheeled vehicle through a retractable apparatus coupled to the wheeled vehicle, wherein the jump-off platform retractable apparatus is configured to at least move between a non bungy jumping position and a bungy jumping position, and wherein retractable apparatus includes a jump-off platform and a rigging frame or equivalent to which a bungy cord tethering a bungy jumper may be attached.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

Herein disclosed is a mobile golf simulation system, more particularly, a double-bayed golf simulator apparatus mounted to a wheeled trailer that may be readily transported and deployed to remote, particularly outdoor locations. The mobile golf simulation system of the present invention is uniquely designed to include a projection system installed beneath a floating floor that, along with right and left drop-down walls, allows for the creation of an open air platform from which a user may play a realistic form of virtual golf, hitting his ball into a built-in screen.
