Very very preliminary. Starting on the basis of the ACA'S Sierra Cascades route. We may get underway at Lake Isabella and ride the SC up to Ellensburg (WA) and then Seattle.

I'll look into the course profile before either committing to the idea or raising issues with the kids.

(wrt profile -- I find it useful to obtain a gpx file from a preliminary gMaps route. I'll run the data on an Excel spreadsheet to locate critical points -- just did a test run with data from a killer-hill near where I live, that I was unable to climb loaded. Turns out that the gradient reaches 30% (!) and is solidly above 15% on 400 meters or so. Even pushing the bike was challenging. It is these kinds of obstacles that concern me the most. Also wanted to point out that the data used by gpsVizualiser is terrific.)
