How much space can I waste?

Lets see if this works: a roughly 1000x10,000 pixel panorama of the Walnut Creek, Concord, Dublin, Martinez, Pleasant Hill, Villejo, Richmond area from the 4000 foot mountain at the end of the road. Napa is off the right edge, and if you enlarge it enough, you can see San Francisco way in the background on the left.

Ahh, aparently there is a pseudo-sane limit on stuff you can put up here.

Anyhooo. Here's the smaller version with some landmarks.
