Yes I'm feeling the same way. It takes about 40 minutes to get to Narrabeen Lake from where I live and about 45 minutes to Kyeemagh. To get to Kyeemagh tolls of $3.00 are paid for the tunnel and I think $4.50 for the Eastern Distributor on the way back.
I used to drive through the city to avoid the toll but the traffic is so busy and I don't like driving down Oxford Street in my van in the early evening

. So its now the ED for me. However last Saturday there was a massive traffic jam on the ED so we got home driving all through the inner city and stuff.
The western park at Narrabeen Lake as its such a great place to have a BBQ and just relax under the gum trees. You tune out from the roar of the traffic and it becomes quite peaceful. The windsurfing can be good there too on a NE wind.
