I've been using the SA maps for years and am always amazed at the inaccuracy. They still don't have the 102 here in Mesa correct after at least three years. That's a major bypass around the city, and now it's being expanded.
They still show the Taylor Street bridge in downtown Chicago. Hasn't been there in decades and decades. The streets around the neighborhood where I lived were all wrong, and the neighborhood was built over the old Dearborn Station rr tracks back in the 70s. No, maybe late 60s. These are major downtown neighborhoods, not little lakeside developments 45 miles out in the country.
I don't even want to talk about the nutty route they gave me from Portland ME to Belfast, going down unmarked roads. Probably the folks at Delorme knew all these backwoods routes, but I sure couldn't guess what they meant.
I got the new Topo from Delorme. They're starting to include routing in that software now, so you can get some idea of terrain on a trip.
S&T is $15?
