Love these initiatives!
But...be aware that there is a similar one planned in the UK (at 31 March 2019) with 600 cars I believe : see https://www.volvoforums.org.uk/showthread.php?t=285437
AND
There was a similar yearly event in The Netherlands this year with +2000 cars, they came from all over Europe, Ask Jared, he has been there!
Should be one in 2019 again, and heared they might do the Guiness Book Of Records thing also.
