A modular rotatable disc-target for competitive games provides an easily dismantling and easily transportable goal that can be reconfigured to increase or decrease the difficulty of a competitive game. The modular rotatable disc-target for competitive game has a goal frame, a first goal post, a second goal post, a base frame, and a locking mechanism. Players playing the competitive game attempt to propel a disc-shaped projectile through the goal frame to win the game. The goal frame is rotatably supported on opposite ends by the first goal post and the second goal post. The base frame prevents the goal frame from being displaced from the desired position on the playing field.

Players can choose between different difficulty levels by using the locking mechanism to lock the rotation angle of the goal frame. This makes it more difficult to propel the disc-shaped throwing object past the goal frame.

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.
