There's a secret park under I-90. Weird place. Some sort of power spot full of odd syncronicities.

Odd: the park is the site of the underwater power transmission lines crossing Lake Washington. In the real world they have the under-space roped off for construction. Explore it on Google Streetview. That link is not a photo, it's a streetview VR map.

Odd: the Streetview of that I-90 park exposes the Streetview car ...towing the Google Bicycle trailer, and you can move along the sidewalks, go out on the pier, wherever the Google Bicycle went. Even climb the stairs.. Don't forget to click/drag every view, to see the bike-rider's shirtsleeves and bald patch. Also look behind Google Bicycle trailer to find bored helper. Here's another view.. Now go and find the glass window where you can see the google bicycle reflected. (Appears to be a normal bike towing a 3ft silver box w/bike wheels.)

Oh geeze, I just hit a time fracture, and the Streetview car/trailer vanished, and it's a sunny day, and now we're trapped in the realitybranch with the playground equipment. Those PortalEdges don't look sharp, but I wouldn't stick my hand in there if I were you. Drive all the way around the park and originalworld reappears again. Clearly requires a 720deg rotation to return to the original orientation. (multiply-connected topology! Must be caused by all that iron and concrete above.)

Sunnyworld version and cloudyworld, but you can't get between them by walking.
