I just put one up. I went the route and obtained a permit, but did have
a PE run the calcs. I found that the 4 foot hole was really overkill for
my area/soil type. I did go 4 but could have gone as shallow as 3. As
far as getting thru that, I don't have any experience other then a
jackhammer...
Good luck,
A.G. Ardon
