Land "owners" at one time or another will have "border security" issues.
Cattle usually leave "good impressions" behind (I should say 'from behind') ;-)
I think ผักแว่น loves water, but it can't swim.
Perhaps, a rescue to 'wet' land or edge of water would be more life saving.
A little cottage in the country for relaxation (or extra work) at weekends is a dream.
