We do not drill holes in them, and use black tape, instead of "zip ties". The ties break when it gets real cold,(below 0)
We advise people to have tape handy in case the ties break. We have the ties started for them on the block so all they have to do is insert the block and tighten the tie. We have the blocks prenumbered with the team numbers. We have all the blocks gathered together with a split piece of pvc pipe thru the ties.
