I have never had to wait for the light at 283 (Bay Dr.) and 98 (maybe I am heavy enough for the pad!

)
Actually, there is always a car on every light change that will trip the light for you.
It's not a big deal- I wait, I look, I go. I was a bit nervous the first time, but now it is no big deal. The cars blowing by me doing 60 on Bay Dr. scare me more- that bike path loks wide, but it isn't really!
Organicmama, my only caution to those with kids is that it is hard to get going with kids on the back of the bike and I don't know if you would have enough time to get across. Also, you might want to check the distance- it is really tough hauling one kid on the back of a bike (Bdarg is the hauler when Kate is with us, and using a tandem so she can "help"), so I can't imagine getting 2 kids down to 30-A, ride around, then get back "up" to the neighborhood. She gets tired pedaling on the tandem, so I am pretty certain we are a year or two away from even thinking that she could pedal down and back by herself.
