The Rillito River path is a great place for a late-night stroll or bicycle ride.
Back in the 1980’s, we could drive in the river bed of the Rillito, it was dry most of the year. Tucson had an event named the Rillito River Regatta. Entries in the event would convert their 4X4’s into floats which resembled water craft, then paraded then down the dry river bed, it was quite a sight.
