Yes, there were quite a number of herds with calves born in early 2006, including in ND, SD, IA, MT and elsewhere. Generally good results and he was used again by many of the customers for 2007. Based on what has been seen as they develop, I think he'll work. If you want more detail contact me through my site http://www.evergreenangus.com or Bill Hodge at SustainableGenetics.com.
There are several nice younger Waigroup bulls available now, too.
I just saw an ad for a ND sale with 41/97 listed as one of the sires, but can't find the ID just now.
