UNLV or UNR would be obvious choices for an in-state safety. I would also look at schools within the WUE (Western Undergrad Exchange) where you would pay reduced tution. Schools like Arizona State where you can see how much merit you could possibly get using their Merit scholarship calculator:

Again, you need to figure out what you and your family can afford to pay each year. The top schools like Harvard, Princeton, Yale give great need-based financial aid but they do not offer merit aid.
