You will want to restrict your visits to Tuesdays and Wednesdays since those are the only full days that the legislature is in town. Explain what sort of demonstration you intend, and let them know that both faculty and students will be involved. Contact Don Wildman, and he will help to steer you through the maze. Once you've got a date, contact a senator and a representative from your district and ask for them to arrange to have the students recognized on the floor of the House and the floor of the Senate. The ideal time for the students to be recognized is at the beginning of each session.
Sessions usually start in the afternoon, but sometimes they start in the morning.
The Senate and House set their schedules independently. Usually, they start at different times, but sometimes they start at the same time. You'll need to check at the Information Desk in the front lobby when you arrive. Also double-check with the secretaries of your senator and representative who are arranging for the recognition. Ask Ms. Kapp if President Lancaster is available to put in an appearance on the day you'll be there.
