Anyone in Sussex, other than the NIMBYs in Charlwood, should vote for LGW as it will bring a massive boost to the local economy.
The NIMBY's should just move ASAP, the airport has been there longer than they have, should have thought about this earlier.
The proposed second runway for Gatwick is to the South of the existing runway and as such will not really affect the residents of Charlwood.
On a personal basis I preferred the Northern runway proposal as under those plans our land would be subject to compulsory purchase for airport warehousing!
