What have you built? Have you ever dug a tunnel?

Also, do bongs count?

My garndfather in law works on railways for a hobby. He has helped build railways in the US, China, UK, and Poland. He has a steam hammer in his garden and many old cars.

When I was a kid, me and a friend tried to dig a tunnel from his garden into his living room. We did not get far.

then later i worked construction too. i've made some pretty big sculptures but none that were very durable -- for years a large thing i did was in the foyer to photographer michael macioce's studio in nyc. he took a few pictures in front of it before it crumbled, notably one with tom cora...

When I was a child of approximately 5 years old, my brother and I, together with assorted kids from the neighborhood, spent several hours excavating a large pit in our back yard, behind the garage where our activities were not easy to see from the house. The avowed purpose was to build the coolest underground clubhouse in the known universe. We had to fill it back in the next day.

A few years later, I participated in the building of another clubhouse, out of various 2x4s and pieces of plywood, in the back yard of my best friend, who had three younger brothers to assist us. My friend lied to his parents and told them that the workers at the construction site a block away (where they were putting up a church) had told us to take whatever scraps we wanted. The truth is that we never asked permission, but unilaterally decided to raid the scrap pile on the principle that "it looked like no one would care if we helped ourselves". That clubhouse remained for most of a decade. As we grew taller, we just dug the dirt floor lower.
