Peds, kids, dogs, joggers, walkers, etc. It's a very popular path. I ride over there all the time. Posted speed limit is 10 mph, but have never seen anyone enforcing it. Sometimes I think it should be enforced because it's a multi-use path and cyclists running thru at 20+ mph is not appropriate.
Weekend mornings are the busiest. I've been there during the week and often the traffic is very light.
