When my field was new I would leave it up over night and had little problems, but after time and normal wear and tear on the field, the bungee cords will break down, so one night a sudden wind storm came through and blow them away and the next morning my team and I had to go on a bunker finding mission, 8 of them blow over a half mile away over a barb wire fence across a corn field over a pond and got caught in some woods and every one got holes in them. It wasn't a fun way to start practice. Now we drop bunkers every night. We have 4 leaf bowers now and it takes us less then 20 minutes to blow up an entire xball field, it's worth it for us to take them down every night

.
We run 2 bulk tanks with a 10 CFM compressor and never run out of air with over 30 people filling.
Hope that may help
Love
Brad
