If anyone fancies a trip to the Tank Museum http://tankmuseum.org, we have a limited number of free weekday tickets at Wikimedia UK. Coincidentally they are not valid during Wikimania itself, but could make a nice day trip for next week.
Tripods are allowed providing you are sensible about where you use them and it isn't too busy.
We have a wish list of things to photograph there https://wikimedia.org.uk/wiki/Tank_Museum_2014, and a blog post from Mightyhansa https://blog.wikimedia.org.uk/2014/07/a-trip-to-the-tank-museum/ who went there recently.
To request a ticket email me at GLAM@Wikimedia.org.uk.
There are trains from Waterloo station http://tankmuseum.org/find_us.
