Hey Mandy! Bring a mat to put under your speakers. Make sure your power inverter has the wattage to handle the speaker output. Also bring a plastic drop cloth in the event of rain (which will not happen!).
You need to bring long ties...the ones with the wide straps that you connect together and then crank to tighten? They have hooks on either end and then a metal buckle thing that the band rolls into and you crank it to tighten it down. Not sure how to explain it. You'll need a couple to secure them to the roof rack of the van.
Be sure to email our crew captain if you have questions as that's the best way to reach the SWEEP TEAM members.
