I spent opening weekend in SW OK. This was mostly a scouting trip for me. Saw lots of sign and glassed up a couple of does including a mule deer doe.
I knew there was going to be some elevation change based on staring at google earth for hours this off season, but I was totally unprepared. There was a tall mesa/ridgeline that I was trying to get up before light, but had to cross a creek on the way there. Come to find out, there is a 10' mud bank on the opposite side of the creek. It took me a while to find a place to cross and I didn't get up top till about 9am. Think I missed a lot of deer movement getting up there so late on an early season day.
To top it off, every brush that I thought was going to be 3'-4' tall was 6'-10'.
In addition to glassing I put about 10 miles on the boots in a day and a half checking all the spots I marked as possible areas to sit. Sat a promising looking funnel that night, but didn't see anything. Wind was perfect, I'm guessing they're just using it after dark.
Also my first trip with a new pack and frame that I made myself. Worked flawlessly.
