That would be an ambitious goal. Not including the bonus cache, an optimized route from my house is 333 miles.
And that's not including any of the hiking involved!
It took us five days (spread over several weekends) to put them out, but we didn't spend whole days at it. We did six of them in one day: Mercury, Earth, Mars, Ceres, Bonus and Jupiter, but then got bogged down with all of the driving.
The only real hike is for Earth and Mars (which are pretty close to one another). The rest of them that aren't driveups are accessible by mountain bike, which makes them take way less time.
We're both really impressed that tomison got the whole thing done in three days, especially since he did it without a bike.
