I have a soft spot for these grounds
Aldershot, Southend, Luton - great atmosphere with barrel shaped roof over the stand.
Grounds with traditional terracing rather than "rail standing": Carlisle, Kettering, Accrington, Hayes and Yeading, Accrington.
Modern terracing like Burton, Morecambe
Quirky grounds like St Albans with a tree in the terrace?, Histon which when I first went, had a drop down fence panel along one side for a kebab van to pull up, Lewes and the Dripping Pan. Palm trees at Eastbourne.
Home fans' traditions: the air raid siren at AFC Sudbury, the guys with the bell at Grays, changing ends at half time at Tonbridge Angels.
Grounds with a view: Merthyr Tydfil looking over the valley, Northwich Victoria with the industrial plant looming over it, Tamworth and the ski centre, Dumbarton with only one stand , one of the Scottish pre-seasons with a huge crane over the Clyde.
Great food : Kidderminster obviously , Burton for faggots and gravy and mushy peas, Sunderland parmo, Woking amazing baps.
