For our last road trip while we are in the UK we rented a car and headed to Rye, a 2 1/2 hour drive South East of London.  We started our morning at Pett Level Beach.  Online, I read during low tide you are able to see stumps of ancient trees which are part of a fossilized forest dating back to the most recent ice age.  Luckily we came at the right time and were able to spot a few of these stumps.
