I know it’s too little too late, but one of the hotels across the street from the convention center, probably the host hotel, had a testing site set up in their facility for foreign attendees to utilize in order to get their affairs in order before returning home.
The FC7 71 hemi cuda and TX9 70 hemi cuda displayed behind me were brought in from western Canada, a harrowing 3000 mile round trip encountering a blizzard on their way here! Hope their trip back was more smooth sailing.
