Pictures from the 2010 Mayday parade are now online in a public Facebook gallery. These are from before and during the parade proper. (Yes, K., I sent HotB the link via e-mail.)
Part II will be in the park, from the festival and MN-StF Picnic. Far fewer pictures, so I may get it done tomorrow.
I took several short videos. That may have to wait until I set up my new system.
