Here's a summary of what the roughly two-week trip to New Mexico cost:
I traveled 1,368 miles. Average mpg was 8.93. Total gas cost was $268.29 for 118 gallons of gas, at an average cost of $2.27 per gallon. Fuel cost was $14.90 per day, $0.255 per mi. Carbon footprint: 2,290 pounds of CO2. (The preceding was brought to you by the wonderful "Road Trip" iOS app)
Camping costs totaled $84... an average of $7 per night. Forest service ($7.50/night) and BLM ($9/night) camp fees were reduced by 50% because of my senior discount. I stayed 3 nights with friends and 1 night dry camping in a parking lot.
Food costs, groceries and eating out, totaled $309.34. I brought home a lot of the groceries I bought at my last shopping trip at Walmart in Deming.
So total outlay for 13 days on the road was about $660. 13 days of my regular "household" expenses at home would have cost, on average, $400.
I can do this! *grin*
