Celebrating NCN's 20th Year

Looking around for ideas on what we could do extra on top of attending the Grantham Green Fayre in August and a possible pending Discovery Day in October as regards to give advice, information and to inform people of Sustrans and the NCN which as you know is 20 this year.
One idea was to have a display in the Grantham library's display cabinet, after talking with the Manager of the library for ideas it was felt this might not be best as it would cost £20 to have, another idea given from the staff was to have a drop in surgery where we could have a table at the entrance of the library and have an array of information to hand and would be offered for free. When asking the best day to hold, a Wednesday a.m. when children come for storytelling and a Saturday a.m. was though best.
I'm thinking this is something we could hold in May, maybe Saturday 16th and Wednesday 20th just before the bank holiday weekend.
It would be great for you to have a think about this over the coming weekend and if your able to get back to me next week if you feel it is a good idea and if you feel it is something you would like to help out on one or both days for an hour or two. I think just having 2 persons present would be enough and it would give a great opportunity for you to to help out.
