I see things in numbers. Must be the engineer in me. It was no different when a few members of the 234th Intelligence Squadron and I hit the trail determined to hike to the top of Half Dome in Yosemite Valley. So here are the numbers of our Half Dome hike:

33, 319   number of steps to top of Half Dome and back (Sam counted)
9,600      elevation, in feet, gained and lost to top of Half Dome and back
16           number of miles to top of Half Dome and back
9              number of hours to top of Half Dome and back
1              numbers of time I feel it necessary, in my life, to go to top of Half Dome and  back

0410     time we left the house
10           number of minutes we left late
0700     time we hit the trail
90           number of minutes we hit the trail late
1              number of couples lost (left) in parking lot so we would no longer be late

45.24     money I spent on gas because someone forgot their wallet
28.32     money I spent on pizza and soda because someone forgot their wallet
12.18     money I spent on refreshments because someone forgot their wallet
1               number of people that, in the future, will ensure no one forgets their wallet

16           liters of water drank by three of us
3               additional liters of water one of the three should have drank to prevent passing out due to dehydration
1              amount of ‘good’ smacks it took to bring dehydrated person back to reality

400   distance in feet of the final ascent of half dome
2         number of cables the average person needs to make the final ascent and descend half dome
1          number of cables one of us needed to descend half dome (obviously not having a wallet makes it easier to descend half dome)

5 hikers spent 9 hours crossing 16 miles, reaching a summit of 8,694 feet and returning to the valley floor, resulting in 1 glorious trip.
