Not much in Marr, as you found out. I have driven through it 1000s and 1000s of times. At one point I was driving through it 12 times a week at least. Sometimes go walking up there but it's actually lethal trying to back back to the A1 from that point and the entire road until you hit Scawsby. Hickleton is far more interesting and has a huge amount of history for a small village.
