Bring a good pair of boots and a loud box call. Merriam's in the hills cover a lot of ground, you you will need to as well. It's not uncommon to walk 10-15 miles a day prospecting for a bird. When the weather is nice its very enjoyable. Something about climbing around pine covered ridges on a fine May morning listening to gobbles is good for the soul. Those snow white tipped gobblers up at elevation absolutely GLOW in the morning sun. Almost too pretty to shoot. You see a lot of wildlife too. We have seen elk, bighorn sheep, plenty of deer etc. Have yet to see a lion while hunting, but there is always plenty of sign and I'm sure they have seen us. If you can roost one, it will help. Every year I run into a few that use the same roost areas night after night the way easterns do, but this is typically not the norm. He will be there for the next mornings hunt, but could be miles away the following day. You can hunt all day out there, so take advantage of it. Late morning/early afternoon can be really good. One spring a couple years ago 3 of us tagged out on consecutive days between 10:45 and 11:15 AM. I'd say probably 1 in 4 birds we have killed in the hills have been off the roost. 2 out of 4 in late morning/early afternoon, and another 1 in 4 in late afternoon. Enjoy your trip, I try to make it out there every spring. It's where I learned to turkey hunt, and still my favorite place to do it.
