After a ride around the cycle track and lunch, we got ready to head home. However, we decided to see if there was anything unusual in the park and found the a bubble man.
The man responsible for all the bubbles has a nice blog in Japanese. If you are an English reader, you can use Google translate and read it here Yoyogi Shabondama (or see the original web site at 代々木公園@シャボン玉ブログ).
