Actually I have. It was not a low snow year, it was an average snow year in 1986 with a 110 inch base, but at 65 degrees most of JH was unskiable. We left after one day and went to SLC, had the same warm weather but much better skiing. I've discussed the reasons for my opinion on this subject in some detail here before:
You can post all the anecdotal reports you want about epic Jackson days in March, but most destination visitors are booking far in advance and the probability of getting deep powder anytime during a week is in the 15% range: http://www.firsttracksonline.com/boards/viewtopic.php?f=10&t=6822
Based upon 23 years of daily Steamboat snowfall (almost identical to Jackson in quantity, quality and distribution):
About 40% of weeks will have no days of 6+ inches.
30% of weeks will have one day of 6-11 inches.
15% of weeks will have 2 days of 6-11 inches.
Only the top 15% of weeks will have at least one day of 12+ inches.
The top 10% of weeks will have 3 or more days of 6+ inches.
If you think I'm exaggerating about needing the 12+ day for good conditions late season, read this TR (not mine) from February 2004: http://www.firsttracksonline.com/boards/viewtopic.php?f=3&t=5540
85+% of the time you are far better off at Snowbird during late season. I have also experienced Jackson in optimal conditions http://www.firsttracksonline.com/boards/viewtopic.php?t=1717 (thanks again to Bob Peters for making it more so) and completely understand the attraction. The original poster, unlike most destination visitors, is willing to be flexible and make the call at the last minute.
