I've started on the Cloverland Series (Pittsburgh is up 2 games to 0), but I'm also at a point where I just finished one of the stadia for Alt-1915's Spring Training and thought I'd pause before jumping into the next one. Since my last stadium post, I've made five more: West Washington St. Park in Indianapolis, Pelican Stadium in New Orleans, Parkway Stadium in Louisville, Plant Park in Tampa, and Whittington Park in Hot Springs. The latter two figure to feature in Spring Training and I tried to set them up in their mid-1910s configuration when I could. The first three are more mixed--Indianapolis is definitely set up for mid-teens, while New Orleans is more mid-1920s and Louisville is a bit of a melange that's maybe more late 20s than anything else.
I'm also not honestly sure when/if the first three will get used at this point. A mid-1920s expansion and a Peppers move could make one of them a viable landing spot, though if so I'd need to convince myself which one makes the most sense. By the next likely (to me) era for expansion/relocation, I think all would need to be revamped (and Indianapolis would already have moved to a new stadium, though one that somebody else has modeled already).
Meanwhile, I'm thinking of plowing through three more Spring Training parks at this point--Barr's Field in Jacksonville, Katy Park in Waco, and Beach Park in Galveston. The first two have some decent documentation, but even well-documented parks still have proven to be more difficult than I might have anticipated...
As far as some of the things I was kicking around the last time I was posting about Alt-1915, I'm currently leaning against having the PCL come in as its own league, or at least not a full 8-team league. One of the questions I'm kicking around is how they'd handle territorial rules if they did go the third major league route--I'm imagining that the PCL as a major league wouldn't be allowed to expand into non-PCL regions, and in return the AL/NL wouldn't expand west of...the Rockies? So Denver and Texas are AL/NL regions, and cities that the PCL would be able to expand into would be Phoenix, Vancouver, and...I don't know. Riverside? Honolulu? Vegas? I suppose the PCL needn't get to be bigger than 10-12 teams. That might push the AL/NL expansion and/or the first wave of migration to the South, to Houston and Dallas and New Orleans (if not already taken) and Atlanta? Again, though, lots of years of game time to get through before this is relevant...
