Having a fire made it possible to go this time of year, even though the evenings were chilly our fire, and having a fair few clothes on kept us nice and warm. Unfortunately Wowo is getting really popular so is booked up most weekends this year, but I can highly recommend it for week day trips, or next year.
Noted the fashions of the weekend were mostly wellies, and shorts - not necessarily together but makes me glad I've invested in a pair of shorts for the summer. Next camping trip to Wareham in two weeks time!
