What makes this design so difficult is that it's on the ground, so it has to be flat; the material has to be sturdy enough to stand up to foot and wheeled traffic, but light enough to break with a crowbar if needed; and it has to be simple enough to open for utility workers to learn it and for civilians to be able to figure it out. This seems like a really worthy design project. Anyone know a high school science or civics teacher? <a href="https://infosec.exchange/tags/scienceProject" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>scienceProject</span></a> <a href="https://infosec.exchange/tags/civicsProject" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>civicsProject</span></a> <a href="https://infosec.exchange/tags/utilityCover" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>utilityCover</span></a> <a href="https://infosec.exchange/tags/saveTheBees" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>saveTheBees</span></a></p>
