I've seen the stories about long waits at SC's in CA during holiday weekends. We are considering making a trip on the Friday of Memorial Day weekend -- and I'm looking for input on whether we have a decent likelihood of having to wait for a supercharger at Independence, MO, Columbia, MO, St. Louis, Mo, Springfield, IL, and/or Bloomington, IL. Obviously, nobody can guarantee anything. But for those of you who have used those SC on holiday weekends, have they ever been full or close to full? This will be my spouse's inaugural road trip and if we end up waiting 30 minutes to get our 30 minute charge even once, I'll get an earful.
