Not a BRC-led event, but there should be some great trail running energy and plenty of trail porn!
Sadly, public transit to Chrissy Field area isn't great. Given that it is a weeknight, if people are interested in carpooling, maybe indicate "8 pm" or "10 pm" for when you'd like to leave to return (at intermission or at the end).
Seats open at 5 pm, there will be a food truck available for clam chowder purchase. Films start about 6, with an intermission near 8, then continuing to about 10 pm. Beer and raffle included. Suggesting to arrive by 5:30 pm.
$8 on ultrasignup, $10 at the door.
