I always take the 10, but on holiday weekends I go to Blythe and up the 95 on the AZ side because there is a lot less traffic that is trying to kill you going across 177/62 "Rice Road".

the 40 has some construction going on where its down to one lane thier was a big crash on the 95s south of the 40 they had it closed dont know if its open yet

40 to the 95 to get to havasu.

10 to rice road to get to parker.

i drove out there friday night...left OC around 730.....no traffic on the 91  ....hit the usual traffic on the 15 between the 210 and the 215.....wide open the rest of the way.

on the way home traffic got a little thick, but not too bad through victorville (victimville) ....and that was it.

made it home in about 4 hours...make it out there in about 5.
