It’s an interesting piece of equipment on the bicycle loop in Tucson. It records the number of cyclists and pedestrians, which would include roller-bladers, joggers, runners, along with walkers all passing the counter each day and provides totals for the year. This is definitely one of the busier spots where people are on the loop. Kudos to all using this multi-use path! (You may even see some wildlife while out there. I bet the roadrunner wished to be counted!)
