So this year for Halloween, Alex went as Super Grover:
Nathan was Matt Smith's Doctor Who:
I gave out candy as Cookie Monster:
Jenn created a pumpkin Dalek for the front of the house:
...as well as the usual pepper-o-lanterns, this one a cyber-man pepper-o-lantern:
...and I added the popular disco lights over the garage (they spin, and are very popular with the kids when they come up) and a black light at the front porch. Jenn did the front door up as a Tardis, which was neat too.
