Turning to the Tale of the Years,
In 2912 (=SR1312 right!?) - The White Wolves invaded the Shire and great floods finally devastated Tharbad.
Therefore much potential for wolf attacks as well as trolls, trouble crossing rivers, possibly even trouble crossing rivers due to troll bridges while chased by wolves? (on no account allow your characters to mention billy goats!)
There could be a tragic scene of Chieftain Argonui of the Dunedain (can't quite figure from t'internet whether he died or retired in 2912) or the joyous accession of Arador (Aragorn's grandpa)
On a happier note you could always meet young Arathorn (39) (perhaps aiding in the whole wolf/troll/flood scenario) and even be invited to Gilraen's 5th birthday party at Rivendell!
I for one hope there was lots of jelly and trifle and that Mithrandir turned up to do the magic tricks !
And you could shamelessly borrow plot from the Barrowdowns itself!
