Why does this mention the U.S.?
<p>There's a company near where I live called House of Air; it's a trampolining thing so, naturally, it has a waiver which explains as specifically as possible the many and varied ways you could accidentally die / become completely paralyzed.</p>

<p>Naturally, it makes for light and fun reading.</p>

<p>Most of it makes perfect sense, until this part (emphasis mine):</p>

<blockquote>
  <p>Waiver of Liability for Ordinary Negligence of House of Air</p>
  
  <p>In consideration of permission to use the property, facilities,
  equipment, and services of House of Air, today and on all future
  dates, I (on behalf of myself, my child or ward, my spouse, heirs,
  personal representatives, my estate, my parents and assigns – referred
  to hereafter as “RELEASING PARTIES”) do hereby waive, release,
  discharge and covenant not to sue House of Air, LLC, <strong>the United States
  of America</strong>, and The Presidio Trust, and their respective owners,
  directors, officers, employees, volunteers, independent contractors,
  agents, affiliates, successors, assigns, and equipment suppliers —
  referred to hereafter as “PROTECTED PARTIES”) from liability from any
  and all claims arising from the use of the House of Air facilities
  including any injury resulting from the ordinary negligence of the
  PROTECTED PARTIES.</p>
</blockquote>

<p>I should specify- I'm in the U.S., so I'm guessing that has something to do with why that's in there.</p>

<p>But still, why on earth is it specifying that I can't sue my country? I haven't read all <strong>that</strong> many waivers of liability, but nonetheless this isn't the first one I've read, and I've never seen that particular clause before.</p>

<p>I am somewhat nonplussed.</p>

<p>House of Air is located in the Golden Gate National Recreation Area, in land owned by the US government and managed by the Presidio Trust (a corporation wholly owned by the US government). As the US government owns the land, and a government-owned corporation leased it to House of Air, House of Air's waiver indemnifies them. It looks odd, but it's just because the US government happens to be House of Air's landlord, and House of Air is indemnifying their landlord.</p>
