He he - we run a different setup with go-karts (as we always hated getting whupped by 11 year olds) with time penalties for lighter drivers. Generally taken as stop go penalties. Makes things a little fairer. And they are twin engined 60mph karts - quite amusingly zippy!

Paintball and pub - another two great options. Pub will be in there anyway by default - I'll check out barbeque options, but remember this is Scotland.
