I was thinking of going.
Where in hampshire are you guys meeting up.
Anywhere near the A272/A32 crossing at West Meon hut?
If I can get a kitchen pass, bribe the dog to nick the keys to the shackles I could be there.
BTW metoffice says:
Could be showers in the morning but brightening toward the afternoon.
Temperature about 5-9C
Hold on to your hats (literally) - Winds gusting 45mph

There may be a wind chill to take into account.
