Flying from San Jose into Las Vegas

HND Henderson Executive
LAS McCarran International
LSV Nellis Afb
VGT North Las Vegas

I am travelling to Las Vegas and am thinking about flying my 172RG
from Reid Hillview in San Jose to Henderson Exec in Vegas.

I'm concerned about crossing the mountains and conditions getting
into LV. I was hoping someone could give me some idea how the trip is
from this area. I recently flew from Florida to San Jose in this RG,
so I'm familiar enough with it to pilot the trip - but I wanted to get
an idea from this group - maybe from someone who has done this trip
before.

Thanks

Brian
