I made some ingame notes for all midsummer fires.
What you need is the Addon HandyNotes from wowace and my savedvariable.
HandyNotes download: World of Warcraft Addons - WowAce.com
savedvariables: HandyNotes.lua - File Shared from Box.net - Free Online File Storage
Copy the handynotes.lua into yourwowfolder \ WTF \ account \ youraccountname \ savedvariables
Here are some example screenshots.

Red cross = Horde Fire
Blue square = Alliance Fire
The Notes work with the most mapaddons and should also work with Routes.
Now open wow and have fun with your Notes.
