Well I just picked up one of each of these from the bass pro. 25 pounds each. I put them on different sides of my property. The bucks and does are split up for the most part. I never get a single picture with a buck and a doe in one pic. Anyways, the place I noticed the does traveling the most I put the Hunters Specialties block and the Redhead block where the bucks are traveling most. I'll post pic's results soon for anyone curious about how they work.

Update-

The rains doing a good job weathering it. Deer haven't touched it. Only walk right over it. It's still early yet for em to hit it.

In the last few weeks the activity on my salt licks has really picked up. I haven't used protein blocks but hopefully they will start hitting yours soon so you can get some good pictures.

i havent had much luck on my mineral sites yet either, but the coons have taken a liking to it. I'm hoping to get a salt block out before to long.
