I am wanting to build dirt jumps in my backyard(its like 5 acres so...) Anyways I can not dig the ground because the land is water soaked, and this will cause problemes. Now why I need your help for is to help me find dirt, a lot of it, for cheap. I am rural New York so it might be hard.

My things:
Bowes SLx7
Washburn WG587
Washburn X40Pro
Washburn X50
Washburn HM24
Washburn WR150
Laguna LE200s
Arietta Acoustic
First Act
Valveking 112
