Should be hard without the poem below, but easy with it.
This cache is quite well hidden in a place you won't expect.
For most it's at eye level, no need to crane your neck.
Within a font of knowledge (though one that is quite wee)
With tools to fix velocipedes, use of them is free.
I hope you like this geocache and find it to be fun.
Help us keep the muggles out, put all back when you're done.
Whfg ybbx jvguva gur tnoyr, hc nobir gur obbxf.
Lbh'yy unir gb zbir gur jurry, vg'f abg whfg gurer sbe ybbxf
Just look within the gable, up above the books.
You'll have to move the wheel, it's not just there for looks
