In Autumn my favorite outdoor activity is cycling. It's a really busy season, but sometimes the weather is perfect on a Sunday when I have some free time.
I have three bicycles. My commuting bike is a 27-year-old touring bike that I've overhauled many times. It's great for running around near home. When I want to ride along the Yasu River or other off-road places, I use my 15-year-old mountain bike. For longer rides I ride a Trek 520 road touring bike. It's getting old, too, but it's in very good condition. I keep it indoors and ride it only on weekends.
Today the weather was perfect, so I went for a short, easy ride of about 20 kilometers. About 5 kilometers from my house there's a big, beautiful park, Kibougaoka Bunka Koen (希望が丘文化公園). A wide road passes through the park, and there is also a very nice bike path. There are no motor vehicles in the park, so it's safe and quiet.
Today it was so warm that quite a few young families were having picnics in the park. There were lot of children, and it reminded me of when my wife and I took our boys there more than 20 years ago.
I hope we get more nice weather on Sundays this Autumn. It's really a nice season to spend a few hours on a bicycle.
