Question #1: Does anyone know where to find a surplus of thrown weapons such as hatchets and knives?

Question #2: Where can I find an abundance of White Horsenettle?

Question #3 A: Why can I not retrieve my thrown weapons after I throw them?

Question #3 B: Is it a bug?

Thanks in advance.

2 -between Goodsprings and Primm on both sides of highway. You can collect there some 15-20 (I was not counting) pieces each 3 days. There is one plant in Goodsprings directly.

3 A -because developers did non make them retrievable.

3 B -no, just bad design.
