HighnDry,
I've mostly used MyTopos in the past, too; for non-Quetico travel, anyway. Their ability to "customize" map coverage & detail was a real plus. This time, however, I got a little frustrated getting it to work the way I wanted to regarding Atikaki. Also, a couple years back, a security breach occurred on the MyTopo website. Apparently, hackers got into their database of users' personal information. Appropriately enough, an alert was sent out to users, urging them to reset passwords, etc. Since then, though, I've been cautious about using them.
Bottom line: I looked elsewhere and found what I was looking for in Maptown, making it an easy decision. Mossback jumped on it & got us both laminated sets of each. I've been eyeballing mine for a month and they look great.
Regarding travel dates, I'll defer to Marten. Our tentative plans are to fly in with him @July 13th and fly back out @July 28th. There will be some west-to-east travel in between. I believe Marten intends to stay in the park a few weeks longer. His specific dates will likely depend upon the logistics of other possible participants flying in or out.
My thinking: pent-up camping demand for Quetico competing over diminished campsite availability (due to last year's major fires) may lead to something less than the wilderness experience I seek. Atikaki appears to be a very attractive option. Having a knowledgeable leader in Marten seals the deal for me.
Let's just hope neither flames nor virus bugs mess it up for us.
Later,
Jimbo
