@Maurice BunnThere is a difference between support and involvement or participation.My wife supports me as a I take on new music projects and students when teaching music.  

I applied everywhere and Chipotle Mexican Grill was the first to offer me a crew position at $8.50/hr. 3 weeks in I was offered a kitchen manager position.

I read here somewhere that it's in the same category as loud music (even if before curfew), but not sure.

Mexican palm?

I would use desert grasses to  landscape, like mexican feather grass (Nassella or Stipa tenuissima), and  plant a few New Mexico Privet trees for height if you can find a spot.

Most of the time its loud music playing and some times elevated voices.

The noise is from movement in the unit, not music, partying, etc.

Spending time with family and friends, organizing volunteer work at homeless shelters, living an active and healthy life and helping other to do the same, traveling, and playing music with his band are among the many different things Kevin values.
