1) After you hit Searchlight and Laughlin, you can come back West on 164 to I-15. Maybe skip Searchlight and stop on the way back, later in the day? (either way 164 and 95 intersect in Searchlight.) Watch out for dogs sleeping on the highway. 164 is a rural road.

2) Stop at the tourist information center off the Interstate, because they have some coupons there, sometimes, that you can't get in Las Vegas.

3) Have fun and submit a "mission report" when you return.
