They have sand pits at Kenmore, but they're only at a single distance. I can't remember which distance off the top of my head. 30 or 40 years I think. I don't know if they'd let you bring a block or not, couldn't hurt to call and ask. Might be a member only type deal to bring a block in and shoot it. The sand pits are open for anyone to use though. I've thought about taking my chrono out there, but I figured they'd be against it, I know chrono's on the gun range are members only, so I never bothered to ask about doing it on the archery range.
