i don't have a backyard ...
and i made it in the woods outside of my college, the last 2 weeks of our class we spent outside
and i was actually getting really nervous because i had to make the monument right there, in the woods, and it was gonna rain.
but as you can see i made it .... and i think this thing is actually gonna last for a while
btw if you were wondering how it was done, i layed out the base from rocks that i got from around the woods and then just puct concrete over it ... hell of a job
but, why does it scare you Graham ?
