ウォーキング・コースの風景１ (Scenery in the Courses of My Walking Exercise 1)

　写真は堺市・石津川と夏の空、2010年8月9日に撮影。中央遠くにわずかに見える山々は、大阪府と和歌山県を隔てる和泉山脈。

The photo, taken on August 9, 2010, shows Ishizu River in Sakai and the summer sky. The distant mountains seen a little at the center are part of Izumi Mountain Range, which separates Osaka and Wakayama Prefectures.

About Blog Posts

[From chiamai, about my blog post "なぜセミの逃げ足が速くなったか (Why Cicadas Fly Away So Quickly These Days?)" (http://dlvr.it/3x5ZS)] The cicada in the picture of your blog post resembles the cloud of the previous post (http://dlvr.it/3tk4g) (or vice versa), only in a different position.

[In reply to chiamai] Yes, though the cicada made of clouds has a too long tail. In the photo of the day before yesterday (http://dlvr.it/3rYxY), you see the children who go to catch cicadas.

[From chiamai] Thanks for your post on Prof. Cabibbo, I would have missed that article otherwise.
