No, not recently. I've only done it twice since living here.
Once as a day hike in 2004 or 2005, don't remember. And then as a 2 night backpack in 2010.
It's longer than Floral Park at what, 17-18 miles? But much easier terrain I would think.
If I do Floral Park, I'll only need to get to Sperry Chalet which is about 13 miles.
Depending on my route finding, stops to rest, picture taking, gawking, yakking with people I may find on the glacier, etc. .....
It'll probably take me a good 10-12 hours to do those 13 miles.
