Good map source Jimbo. Thanks. I've used mytopos or something similar in the past to get topos for Canada but I like the maptown versions, especially if I can get them in waterproof versions. And now, thanks to Marten, I think I can locate Shiver (more or less). I'll have to ask Marten to remind me of the timing of the trips. I'm assuming they are going in around mid-July? to mid-August. If that schedule is different, I'm sure you both will let me know :) I'm looking forward to being part of this, this summer.
