Portland flights were cheaper than Denver for me, and I also have a high school friend in Bend. Liz lived in Boulder one year in college but she's never been to Oregon. 90% of seasons I would see little reason to range beyond Mammoth at this time of year, but we all know this is not a great year in the Sierra.
This is not my first spring trip to Bachelor:
May 3-4, 1990 had corn perfection both days
April 5-9, 2000 had 3 days of corn perfection (plus one more at Mt. Bailey snowcat April 4) and some of my multiple day vertical foot records that still stand.
April 14-15, 2007: http://www.firsttracksonline.com/boards/viewtopic.php?t=3147 40K vertical on April 15.
April 7-8, 2012: http://www.firsttracksonline.com/boards/viewtopic.php?t=10186 All time record 50K on April 7.
June 29-30, 2012: http://www.firsttracksonline.com/boards/viewtopic.php?t=10254 Not the quality of the April/May trips but for that late in the season, amazing! 47K in the 2 days combined.
Utah is having a good corn cycle now, but I'm reading reports from there every spring and it's much less consistent than Bachelor or a normal year at Mammoth. Better to chase powder for Utah skiing as I did last April: http://www.firsttracksonline.com/boards/viewtopic.php?t=10943 . I am jealous of the reports from King Grump & company over the past month, though I have skied 17 days in Utah myself this season.
I thought about Denver/A-Basin, but A-Basin has about 1/4 the terrain of Bachelor and in May I believe the snow to be less consistent. Late April with multiple Front Range areas open (which I've done in 1987 and 1991) would be a more tempting time for me to go there.
