speed bumps

Just returned from a brilliant week at Cirencester Park site, couldn't have wished for better. One small problem though was the new addition of three speed bumps on the approach lane to the site (owned by the local college I think). Myself and a few other caravaners commented about the hight and steepness of these bumps causing the tow hitch to make contact with the bumps. Evidence of which could be seen by the deep grooves in the tarmac. It didn't matter how slowly you went (which is the reason they are there)contact was still made. When it rained, the water was trapped and mini lakes were formed, making the lane very muddy. Apart from that I hope those using the site will have a great time.
