Crystal City Underground is going under https://www.bizjournals.com/washington/news/2024/04/30/crystal-city-underground-closing.html
For a region that’s a bit structurally immune from zaniness and fun, losing the Underground (and the puppet store, cobbler, weird DoD knick-knacks store, etc) seems like a squandered opportunity.
A Somerville Underground would be unstoppably awesome somehow.
