The long, rectangular room has a wide-open feel with its high ceilings and exposed brick walls, and aside from a lack of air conditioning and plumbing, serves as the ideal setting for a tasteful (or madcap) art happening. Sadly, there’s no telling how long the converted baggage building will be available for use as an art space. It belongs to the City of Tampa and is used free of charge by artist collective Experimental Skeleton as a space to display artwork and host artsy happenings — but only as long as it takes for the city to find a paying tenant.
