Luke said, "We're still not clear about the oil thief's motives. On the bright side, it could just be a prank.
On the downside, someone might be trying to stop us from treasure hunting. Every minute we delay, they could find the treasure first."
Walker said, "Without the tricycle motorcycle, it might take us twice as long to reach the canyon floor, and the area is quite large, making it inconvenient to search.
Should we contact the canyon manager to bring some gasoline?"
Luke said, "We've driven further west, getting farther from the rest area. It's hard for the canyon manager to get here quickly."
Morris Dawan suggested, "How about I stay here, wait for the canyon manager to bring the gas, and you two go treasure hunting in the RV. I'll meet up with you once the gas is delivered."
Walker asked, "Can you ride a motorcycle with your foot injury?"
"It hurts a bit to walk, but riding a motorcycle isn't much affected."
