take her for a hike, between castle rock and larkspur there are a bunch of nice trails
ooooo, or go up to estes!
go for a ride up the canyons...or for a picnic. Go for a walk.
or you can be really romantic and write her a love letter. then make clues and have her follow them until she finds it...
romantic dinner at home
ooh art museum is good idea. those are usually free.
i agree, museum is a great idea.
but they are not fun just free

stay in bed all day?
I don't think you like our ideas.
the art museum is free on Saturdays, but I work my second job them. The rest of the time it costs more than a movie
dinner at home is bad, because I am the worlds second worst cook, next to my dad
my girl is very active, staying in bed would drive her nuts.... even if we are busy doing soemthing. ahem
driving these days is expensive with gas prices being as high as they are.
grrr.......
hmmm, active,...hmm...go to an amusement park and have fun
something cheap was the big deal. Ammusement parks cost alot

go on a hike
Dood, grab some Subs, and head to Pike Nat'l Forest via Rampart Range or Perry Park and see the Aspens changin!
Castlewood Canyon is just south of Franktown and that's always fun to hike around.
