I camped over night for the 1st time in the 3 years I have owned my (mega small ) finca last week and all I can say is FLY,S,Fly,S Fly,S and all the rest of huge flying insects !!!also did a bit of digging etc.. and dug up a think not 100% civil war rifle bullet ,"Matormoras" did a bit of searching on net -Battle of the Ebro ? was there fighting   in this area ,or do you think it was from a boar hunter ? :-X
