Fine if you want to never stretch the day, and enjoy landing in places
where unforeseen risks/hidden obstacles can cause expensive damage.

I have landed in more fields than I care to remember, and occasionally
beaten World Champions on competition tasks. I feel no shame in
knowing when the day is over and ending back at the field with an
intact ship ready for the next day.

Chacun a son gout.
