I found Bay Area Bike Tag #430 at Cogswell Marsh Bridge in the Hayward Regional Shoreline. I took a photo of my bike there and rode to a new location for a photo to post of the next tag for others to guess. https://www.reddit.com/r/BAbike/comments/10e1ybg/bike_tag_431_wormsign/ To play you have to guess the location from the photo. Since you've seen my route, you're disqualified from playing this round. (The point of the game is to guess from the photo and get there and to your new tag first.) But there will be more rounds from other players. [edit 1/17: the tag has been found. Now making the ride visible to everyone.] I solved Tag 430 quickly, only a day after it was posted. It had been more than 10 tags since I last played. So there was no waiting period. (10 days or 10 tags is the waiting period for players with 19+ tags.) I've been wanting to set this location as a tag for a while. The title "Wormsign" is a saying from my home planet. (Actually, it's a Dune reference in case you didn't get it.) It means a sandworm has been detected digging underground nearby. But the reference to reality in this tag's location is that this is the spot where the tunnel boring machine will begin digging the downtown San Jose BART subway tunnel probably by next year. TBMs dig sort of like a sandworm, though much slower. The photo as shown includes Caltrain tracks with newly-installed overhead catenary electrical lines, and the overpass of I-880 over the tracks.The empty ground between the fence and the Caltrain tracks is where the BART Santa Clara tunnel portal will be built. To get to the bike tag ride, I took BART from Milpitas to Hayward. On the way back, I had to avoid most of the Guadalupe River Trail due to flooding of road undercrossings - I knew ahead of time it wouldn't be available. So I used Zanker Road instead. My route joined the GRT at SJC Airport.
