Vegas is plural of vega. According to the Real Academia de la Lengua Española, it has three entries:
1. f. Spain. Low, flat and fertile land, generally irrigated by a river or a canal.
2. f. Chile and Ven. Very wet ground.
3. f. Cuba and Ven. Land planted with tobacco.
The origin is from Latin: vaica
Thanks. I prefer the Spain entry. You can get stuck or sink in very wet ground and tobacco is "a major risk factor" as well.
¡Ja! ¡Ja! Yes, the truth is that it is a very, very high risk. I haven't smoked for 8 years but I still remember the aroma of my Borkum Riff in my tobacco pipe or my "puros habanos".
