I was out at Birkdale this afternoon and evening to see a couple movies and while I was outside between the two, I noticed there was a cruise in going on. So I spoke to one of the people there (he was affiliated with the Draco Performance shop) and he tells me that it's something that's been happening for a while now.
So here's the deal: This happens every 3rd Saturday of the month and parking begins at 5:00. We get to park in the grass median in the center of the main drag (which means whomever wanted to come out would need to meet up prior to 5 and then go in together so they'll get to park together).
There was a mix of cars out there, everything from old Sports Cars to American Muscle to Subarus. There was even a turbocharged Volvo 240 out there. I think they could do with some Z cars out there and really think we should participate. The next one should be on July 21st. I'll see what I can do to confirm that.
