Are you interested in rec, Classic, or travel level?
MSI reserves a huge number of practice permits for their rec and Classic programs, and then internally assigns the permits based on coach preference. MSI holding the permit doesn’t guarantee which (if any) team is practicing there. Their travel teams likely practice at Julius West or on another turf field they hold the permit for.
MSI tries to do rec team assignments by neighborhood/school cluster, so if you’re interested in rec for the fall, you will likely be assigned to the closest neighborhood or school team (pending available roster slots) and hopefully the practices won’t be too far from you.
Classic, you try out for teams specifically, so you could restrict the teams you consider by their general practice location.
Travel, I’m sure you can just email MSI and confirm where the travel teams practice.
