[Talk-ca] Logged Canadian Road Trip

[Tim Francois]

A few of the highways I listed we doubled up (the Dempster for one - no 
other choice really!), so there will be two traces for these.

I do have a txt file which logs dates/times and a description at that 
position, be it a POI, fuel, turnout etc. It's not complete by any means 
(it was a holiday after all!!), but it's a start and will keep me busy 
for a bit!!

Another observation I made: the further North I travelled, the more the 
towns/cities seemed to be shifted one way or the other on Navit. I'm not 
sure how to call this one. It could be Navit not processing data 
properly towards the poles, but on the other hand the highways were 
largely on point - it's just when you entered the towns/cities that 
things started to go a bit skewy. A notable example is Whitehorse, YT - 
I was driving through the middle of buildings there - we visited twice 
in two weeks, driving on three separate occasions and at different times 
of the day, but the entire town seems to have dropped South-East for 
some reason!! Other places I noticed this in where Tok, AK (should 
probably be on the Yank mailing list for that) and Dawson City, YT. I 
won't mess around with these places because as soon as you change one 
street, the entire town will have to be updated or the whole place will 
look a mess - just though I'd bring it up!!

Cheers
Tim
