<p>Building on what ucbalumnus said…</p>
<p>It takes about 10 min to walk from Clark Kerr to SE corner of campus.</p>
<p>In the most extreme case – if you have to get to the NW corner of campus, like where the College of Natural Resources is – it takes 15 min to walk (diagonally) from the SE corner to NW corner of campus.</p>
<p>Of course you can always take the perimeter bus around campus.</p>
