I love the Siembra Valles so this had been on my list to try...
I was in Murrieta - my son'e mom lives down there and I drove down for his 8th grade promotion. (He is 5'11" going into 9th grade - needless to say the Freshman Football coach was happy to see him lolol) About a 6.5 hour drive down from here in Modesto.
My buddy from up here was down visiting his mom in Seal Beach at the same time I was down, so they came out to have lunch with my son and I. My buddy stopped by Hi Proof to pick up the order for me. Where are you in SoCal?
