I went through the Okpic Program (winter camping/travel) in the late 1970s and early 1980s with my scout troop.  Lots of fun.  A buddy and I mushed through the Sommers base a couple of years ago while finishing a winter loop back to our truck on Snowbank, and I noticed how much the base has grown over the years.  Glad to see it's prospering.
I assume they send few trips to Quetico anymore (due to the cost, need for passports and RABC, etc), as I paddled over a hundred miles in Quetico last week and didn't encounter a single scout group.
