thanks for suggstion!
route prpoposed very much same suggested by bike shop in Vancouver.
If I were more ambitiout I would do the reverse of the RACK ride on the west side to Ridgefield and then cross I-5 and then old 99 (or equivlenat) north to Woodland.
If the weather is anyathing like today, even the nosiy boring parts through Vancouver Hazeld dell shouldn't be too discouraging. And assuming I make my destination, my freinds will likely suggest Ii use their hottub (or at least their shower!)
