I was going to say, the BC Govn't
used to have really good pdf maps of both Squamish and Harrison, but I can't find them now. All links pointing to them are dead.
Thankfully I have them all backed up!
Only problem is they're really huge, 28 MB just for Squamish, and 5 for the Chilliwack region. But they're great maps. I can either put them up on my ftp site for you to download (would take long if you only have dial up), or I could burn them to CD for you.
Hell, here ya go, one of the pages (the fun part of Lake Harrison, West side). Only around 350KB.
