Ahoy thar me hearties!
T' find this booty, ye'll needs t' take a wee walk down th' Pirates' Cove Greenway. 'Tis hard bein' amongst all these trees, but th' creek pleases me senses an' casts me thoughts t' th' briny deep.
I hid me treasure nearby an' drew a map t' aid in me findin' it again some day. Then, I ripped me map into four pieces. I gave three pieces t' three o' me finest crew, an' kept one fer meself. Me crew hid each o' their pieces in bison tubes along th' greenway.
Ye can see me piece below, but ye'll have t' find th' other three before ye'll be understandin' me cryptic map or be seein' any o' me treasure! Ye should be bringin' a camera or a quill an' ink t' copy th' map pieces into yer own logbook.
Thar's enough space in th' treasure chest fer swappin' some wee trinkets. But don't be leavin' any grub in thar, if ye please.
Ye should be knowin' that some o' th' houses back up right t' th' greenway. So, be warned, matey! Ye may be in plain view o' some landlubbers.
Fair winds t' ye, an' I'll see ye on th' open water, ye salty sea bass! Yarrrrr!
