If you want to try an early season scent yu may want to consider Buck Fever synthetics. The pre/post rut is designed as a curiosity scent. You can make mock scrapes or freshen last years scrapes. Deer will use these "scent post" all year long although the most obvious sign of use is durring the rut.
If you're interested is some interesting reading check this out.

Take it with a grain of salt because they are obviously trying to sell a product but from my experience with their products they are pretty straight shooting.
Good luck.
