If this was court, this wouldn't be allowed (heresay), but;
While climbing Ampersand yesterday (4/10), I bumbed into two guys on the way up wearing crampons. Now there was a good deal of ice along the steeper sections, but they weren't a neccesity.
In chatting with those guys, they were just wearing them after slogging most of the way up Giant without them the day before. They described it as pretty icy still.
Like I said, that's second hand, but it doesn't Suprise me as we saw plenty of snow/ice at 3300', let alone 4500'. Good Luck.
