If it is the existing football ground it could be Boreham Wood FC and Arsenal. Arsenal ladies play there already. The F.A are trying to grow women's football. Throw in the possible entry of Arsenal Reserves into the football league and they may want a bigger stadium. 20k still sounds too big though so I'd say it is a long shot.

I worked in Borehamwood for a number of years, for a well known mobile telecoms operator when they were there.

Borehamwood is a hole of the highest order.

It's got a permanent feel of violence, bubbling away.

The railway station is right at the other end of town, a good 30 minutes walk away from this proposed site.
There's a Wetherspoons about 10 mins from the station, but not a lot else.

When I first started working there, some gypsies moved into a nearby field. They left less than a week later after 'the locals' paid them visits.

Did I mention that the place is a hole of the highest order?

The office which I mentioned used to be used by said mobile telecoms operator.
You're right about Borehamwood though. Couple of Huddersfield fans were staying there (funnily enough in one of the hotels right next to said office block). I told them to go to Shenley.

Aye, far more pubs in Shenley. 4 along the main road, plus The Mops And Brooms nearer B'wood.

Used to be four.
The Black Lion is now an Indian Restaurant, the Queen Adelaide has been knocked down and they're just finishing off the flats built on the site. The King Will's still going, and the White Horse does cracking food and real ale.
I told the Hudds fans to head there, and suggested they stop at the Mops on the way back.
