Sand does not work too well. The structure of both the tunnel and the pit are difficult to maintain in sandy soil. A better alternative in sand is to dig a slightly shallower pit, then make an open-topped trench or two in the sand leading to and from the pit to help increase airflow, covering the trenches with flat rocks, tree bark or whatever is available.FreedomoftheHillshttps://www.blogger.com/profile/11814351046926976038noreply@blogger.comtag:blogger.com,1999:blog-3892567243271381571.post-39339421397012288702011-02-06T04:02:24.137-07:002011-02-06T04:02:24.137-07:00Does the dirt in the top of the tunnel ever collap...Does the dirt in the top of the tunnel ever collapse from being too dry?
