Aye, tis a good point ye be makin thar. I's actually goin fer a bit o a treasure map style (ye fancy). Gaudy colors n' all but more old style and such. I c'n see thoughs how it mights make it a bit hards to see fer a proper sailor (so's I's cans tone it down a bit). As t' the letters n' numbers I must ask ye where you ha' done seen a treasure map that'n didn't have the locations marked in proper letter n' number grid squares. I's see's though the value o smudgin it up a bit as to throw off the foolish whelps. I'll give old grease handed pete the map tonight n' let him ha' his way wit it. Thank ye much fer yer input. I'd offer ye some rum but I is fresh out n all.
