I went to Whitetail on Tuesday afternoon. I was actually pleasantly surprised with the conditions. Skied Angel Drop, Drop in, & Exhibition for four hours. There were very few if any bare spots on these trails. The bare spots that were there were easily avoidable due to the lack of skiers and boarders. Exhibtion had a good line through the bumps and the troughs had no mud, brown spots, or rocks. The one bare spot you can see in the webcam. With some grooming Exhibtion should make it till the weekend. I also thought the terrain park was in good shape. All in all it was well worth the trip.
FYI - Whitetail was offering a full refund/voucher if you didn't like the conditions after an hour of skiing.
