Buffalo's Olympic Park II is here, in the Jazz Age thread:

Messer Street is on my to-do list, but is going to be largely historical fiction and based on one of the contemporary Boston parks--there's not a lot out there for it. I haven't thought about Buffalo's Olympic Park I.
I do have another park that's ready to post here--I'm not totally happy with it, but I don't think I'm going to be able to get it any better so I might as well just post it (later today?)... Next for this thread for me will probably either be trying Messer Street or one of the non-MLB parks for which we have decent info (like in SF or LA)?
