Here is a nice picture of one of the many well maintained parks that are in Boise. Wish I had brought a drink and my lunch, it is ~85F again today (September 26th).
This is a view off of one of the bridges of the Boise river. We used to float down it in inner tubes around once a week all summer. Yes, really! It tends to be kind of cold, though, as most of the water is made from snowmelt.
