Velcro, tape, and hair ties, along with a bunch of nickels in all of my bags to open my VMS in a pinch
But yes, all are a necessity in my taping adventures
And I'm glad for this thread, because I'm all outta bungee cords at the moment some how? So this thread reminded me to grab a container of them the next trip to Wal-Mart or Sam's Club
And gaffer's tape! Damn it's expensive tho!
