And now for something completely different. If you’re free tomorrow night from 5:30-7:30pm (or later for an afterparty), Hollow Earth Radio is sponsoring “Light Rail Dark Rail”, a series of live musical performances onboard Link. Performances start at IDS at 5:30, with “concertgoers” catching a southbound train at 6:00. Once at SeaTac, you’ll have a choice of northbound trains, “Light Rail” or “Dark Rail”, but you won’t know which you’ve chosen until it departs. Expect eclectic local music, nervous security guards, and surely dumbfounded passengers wondering what hit them.
