My husband and I need to find something outdoorsy to do today. He will be off work at 2:00 and then we can go visiting. We are staying in Hayward and would like to do some walking. I have red about Redwood Regional Park and Mt. Diablo, We have no idea how the traffic is to get to or return from either of those places. I am assuming traffic is okay at 2:00 but nor sure about the return traffic. Help us figure out what to do today from 2:00 to about 6:00 p.m. Any other suggestions that the two places I listed are welcome.
