I live just outside of Glasgow, in region 6 that you mentioned. Numbers have bounced back from the terrible winter of 2010-11. You can buy antelope tags thru the draw process which has a deadline of June 1 to apply. Remember , NR are limited to 10% of the draw, unless few residents put in. I know the 900-20 archery tag sold out last year, which was very unusual. I hunt a large ranch in sc Montana, in region 5, there are literally hundreds and hundreds of antelope, the odds of a NR drawing there are about 65% on large portion of the ranch, and 90% on a smaller portion, so even HD's close to each other vary greatly. I take it you are talking rifle hunting and not bow? The antelope season has been set , the general rifle season is Oct. 9-Nov. 14, so if you do decide to hunt deer you have plenty of crossover time to do so.
