driving to 21 casinos. I hit every casino and card room I hadn't visited recently. I went to San Diego,Riverside, & San Berdino counties. It took a tank of gas, and about 7-8 hrs., mapped out a route, the best trip. Most casinos off freeways, and clustered. It was a trip to return a bunch of chips, only worth face, pick up new chips,and cards. LA county, is far from where I live in Riverside county, but you will be in the LA area, so I would think you should go to LA casinos. As, stated in other posts traffic is a problem M-F rush hrs. am & pm you can be stuckin traffic for hours. Sat or Sun best time to go.It will be a fun outing, take pictures, 4-5 hrs you can hit 6-8 casinos in La county. E-mail be if you need maps, or any questions, I've lived in So. Cal. for 75 yrs.
