What's the parking situation at Old Hall these days? Got chatting to the old boy in one of the cottages by the gate and he said that there's a new site manager who keeps the gate locked from 5pm through to 9am. If this is the case, then that would make the site effectively worthless to people who work weekdays and can't often go birding on weekends. Sure, I could walk on from Salcott but I never have more than a couple of hours at a time these days so can't really afford to spend that much time in transit, especially in an evening.
I can however (if you want) give you a lift and drop the car off at the house of a friend in the area.
On the good news, I think Tom (birdpics) and I will be scoping the area for about 7 hours on Tuesday if anyone fancies joining.
