Escape the Well

A weekend music festival on an old farm sounded like great fun… But then you went stumbling drunkenly through a field trying to find a quiet spot to relieve yourself of one-too-many drinks. The old well was boarded-over, but the boards were rotten with age and collapsed under your weight. Down you plummeted to the bottom of the well…. your cries for help are drowned by the tunes from the bands.
Some creative thinking is needed if you are to get out of this jam.
