Safecasting Tamagawa by bike

This is a guest post by Robin Scheibler

Steve and I met Sunday (June 5th) morning at 10am at the hackerspace. After quickly hacking a fix for the batteries of the brand new bGeigie-mini from Akiba, we set off on our bikes, direction of Tamagawa. We first went through Meguro-ku and stopped there to check children parks and schools around Todoroki where Steve used to live.

We continued then down to Tamagawa river. We continued North until Komaimachi, checking on our way the rivers Nogawa and Sengawa.

In Komaimachi, we met with Jeff, Miho and their two kids, Taiga and Jasmin (Steve has a picture of us with the whole family). We checked their balcony and the neighbouring park. Levels detected where low (30cpm air and about 60 ground, i.e. 0.1uS/h air and up to 0.2uS/h on the ground).

We then went down to Tamagawa with the whole family and met some more friends of Steve there. We had a relaxing time playing Frisbee and Soccer. Steve enjoyed some Yoga (picture).

Finally, we went back pretty much the same way back through Meguro-ku and to the Hackerspace. Final map of the ride can be found here.
