Hi all, got an update on the Alfa site re the meet. It states,
"Cars can arrive from 9am but need to be in and set up for 11am at the latest before the museum opens to the public.If leaving early before the museum closes at 5pm, you must be accompanied out slowly for safety reasons. As always at these events, please keep the area tidy and where possible give a donation to the museum for letting the event take place."
I hope this helps and I will see you there.
