Does anyone have a list or know about any high school lineman camps available during the summer dead period?

I'm sure you can go into any University's web site and see if their football program has any upcoming camps. If not, the two weeks is meant for relaxation on the beach.

Not during the dead period but, Kentucky Christian University hosts a "Down and Dirty" camp for linemen only, this is a camp that is hosted around the mid-west and is an excellent lineman camp. At KCU the dates are June 10-12. There are other dates at other locations.

Also, many universities have an all position camp, and a lineman camp, normally back to back dates. I know UK, and UT has one. Just check the football web site for an university that you would be interested in.
