I would say email Kelly Todd with your questions, he is the Laramie area Access Yes guy and was our GW until last fall. He knows the answers to all the questions posed on this thread.

You have to have a permission slip to enter an HMA, if any public land can be access from a public road you can hunt them without an HMA slip unless the rules specifically state they are enrolled in the HMA. Parking along a public road is generally ok, interstate not as much, to access unless the rules state you must park in designated spots.
To access public lands adjacent to an HMA you have to have a permission slip for the HMA to go through to the public lands adjacent.
Carl, MTL, and bullbugle all have valid points and correct info. Sometimes thing get lost in translation so to speak.
Kelly is probably tired if my questions but he always has a pretty prompt answer.
