If it's on a day when I can go, there would be room for 1-2 other people in my car, except that the trunk might be pretty full. if 1-2 people both brought many plants, that might not work.
But one person ought to fit, especially if we can set plants on top of steel shelving, which seems possible if we block them from sliding around.
But some weekends in March will be "taken", I just don't know which ones yet.
I hope I can come!
