The present invention 10 discloses a first embodiment having a straight line apparatus consisting of tubular channels 18 that pass through risers 20 that elevate the channels off the ground. The end risers 22 provide a port 24 on one distal end that allows the user to attach other succeeding lengths of channel 30 to the main structure via couplers 26 that are inserted into the end port 24. The second embodiment 34 provides a curved apparatus, consisting of main tubular channels 32 that pass through main risers 34 that elevate the channels 32 off the ground. The main end risers 42 of the main structure provide ports on one distal end to allow the user to attach other units, via main couplers 40, to expand the apparatus to a larger size. The side channels 36 and risers 38 can be removed and snapped together in a stacked fashion for easy storage and transportation of the device. Main end caps 44 are also provided and are attached to the main end riser port when additional stations are not in use.
