Wister has always been the polar opposite of San Jac in regards to blinds and signage , Besides Tom giving detailed information on how to get to your blind and the hazards of that particular blinds , deep water , over grown etc... the place is pretty easy to navagate. Wister on the other hand can be a pretty intimidating especially for individuals new or newer to the refuge , poorly marked roads , poorly marked blinds , parking areas etc.. and in the past the indiviuals of the refuge were of little help , " ask for directions and they'd point and say "down the road make a right " .
However this year my experience is vastly different than the OP's , parking area was easy to find , lot was clearly marked , blind marker appeared to be new , and when we checked our birds in the refuge associates were more talkative and personable than at anytime in the past.
Anyone can have a bad experience , and waterfowl hunting can really put a person on edge , lack of sleep , long drives , missing shots , the list goes on . That being said with the limited hunting opportunities here in our great state I'd hate to lose one , it may be better to extend the olive branch even if you're in the right and keep ones options open.
Good luck and have a great rest of the season.
