I put concrete in the stand, as well as the bottom 1/3 of the PVC pipe. I also put a small noodle float in the top to help it stay upright....

BUt you bring up a good point. If I put 3 together using "T" fittings they would have a better footing and then use a cinder block in the middle to hold them in place...... That will be my Gen 2 design!
