Nort sure I have managed to do this Ok but take a look at
http://myndit.dogscogs.com/landy.wmv. The clip was captured by my kids (so a bit shaky) and shows an amazing road that floods twice a day at a crazy rate. The first part shows the tide coming in and us heading for higher ground, the mid part is us driving back out as the tide recedes (we went a bit too soon and had to wait a bit for the tide to drop a bit) and the end part is the tide coming back in again (this time with waves...)
Sorry it's a bit long
