Wasn't it Toolbox ages ago that built a ramp out of concrete blocks? cracking idea if you have the space and you can build a structure that is strong enough.
quite theres a line of higher ground little way back could have run ramps from.
guess lhd and driver watching ramps from far side but not much room for error,
presume a spotter out of view. crikey was never struck on getting buses off the
pits at work, and had painted lines to show where outside of bus should be.
