Well, it certainly would be interesting to add those areas, but I agree with Mary-Anne - the extra workload, etc., is a big factor. (Can you say "non-profit" boys and girls?) It would only be do-able if WNP could recruit additional volunteers, from the Haight and Coe Valley, to help shoulder the new responsibilities such an inclusion would bring.
I do have one problem - I certainly know where the Haight is located, but for the life of me, I could not find Cole Valley on my trusty SF map. (The old eyeballs aren't what they used to be.) Paul, can you give me a general idea of its location?
