this touches on the whole topic of how much research to do for a given route before you go. I certainly appreciate knowing that there will be X amount of climbing between point A and B, but perhaps because I have used paper maps so much in the past, I find I have a reticence to using google maps and such to overdo pre-trip research and look at how roads look.
"Over do" is a broad statement, I certainly find google maps streetview and such as great resources, I just question how much research and exact details is necessary. Of course, when saftey issues are at hand (narrow road, windy, lots of traffic etc)--more info is always better, and especially so with travelling with children and perhaps a towed trailer that can be wider.

This is not being critical of your trip planning here Gauvins, but more a general questioning of how much is too much and can take away from some of the "wow" factor of discovering places first hand, or perhaps a better way of putting it, not having a preconceived view , photos etc, of how a place looks before you move through it in person.

I guess I bring this up because one aspect of bike touring, or just biking in general, that I still love, is that sense of adventure and discovering things as you go along. I figure there is a good balance of knowing a certain amount of things, especially when dealing with safety, vs a bit of winging it and taking things as they come and getting that "wow" moment of seeing things for the first time.

**Just saw your addition of that florida cycling calculator--didnt look at it for more than 5 seconds, I guess if it can be a help, great. My first reaction was that it seems like a lot of work, but I guess for some dubious sections, it could help.
My feeling is still that looking at a trip with so much micro planning is not my cup of tea, too much techno and would detract from it--but thats just me.

If you use this, I'm sure others would be curious to hear how it actually works. Thing is you will really only know after doing a trip how and if and to what extent it was a help.
