After careful observation, we are no longer convinced our stingrays are true Milwaukee fans 💛💙.

(Or really… their exhibit is undergoing fiberglass work and they’ll be back in the coming weeks).

The investigation into their Crew loyalty remains ongoing.

We are not concerned with the loyalty of the Ocellate River Stingrays. Those guys passed the vibe check.

After careful observation, our rays have concluded that the Milwaukee Brewers are the best. 💙💛

We’re still reviewing the data but the evidence seems compelling.
