Im glad this started off with Frank Hill
first, to GMann, this is a truly noble endeavor, and respect for taking it on.
i haven't had a chance to look yet, but You's comment here, has me wondering if inevitably a lot of "street skateboarding history" is being overlooked, because for some of us "street skaters," Frankie Hill was a bit down the line historically.
not sure how you're determining a starting point for this history, but if the ollie is a criterion for mapping the earliest points of street skating, Vision's NSA videos at Oceanside were formative for some of us--dare i say--first generation street skaters. specifically Mark Gonzales' parts--in the first one, him ollieing to axle stall on the seat of that picnic table at the end of his run, was a serious historical event in street skating:
there weren't many "video" videos just yet, so if you were a "street skater" at this early time, and wanted to ollie and do other early incarnations of modern street skating, these videos were where you looked for stoke.
same with the original Savanah Slamma and/or the Ohio Skateout--it really was mainly Mark Gonzales and a couple of others, making shit up quicker than the mags could even name the tricks (for instance, Gonz 180 ollie to fakie 50-50 at Ohio skateout:
of course, "Sick Boys" was significant as well, and Julien Stranger's front board's on that Mission handrail were absolutely a "main event in street skateboarding history."
apologies, if i'm carrying on like some old dude, and you may not have intended to go this far back anyway, since "skate videos" devoted to street skating weren't completely a thing yet...
