St Pete city, owner of Trop, is spending $6MM to waterproof exposed portions of stadium (scoreboard, concessions, etc). This is not the roof reoccur,
If roof is deemed irreparable, work may cease. If draining system can be worked out (there is no drainage system), possible that the Rays may play open air. Lord have mercy, I lived in Fla for 18 yrs and summers are tough.
Second consideration is to play in Dunedin (just north of Clearwater/St Pete area). Holds 8300 if memory serves me. Jays do there Spring training there.
