[singlepic id=42 w=320 h=240 float=left]日本猪肉酱汤在日语中写为”猪汁“，是我非常喜欢的日本家庭菜。过一段时间就会做一大锅，因为味道很好，做起来也容易，吃后觉得胃里也很舒服。
”猪汁“里有肥瘦都有的切得很薄的猪肉片，牛蒡，白萝卜，魔芋丝，芋头，香菇，当然还有日本的酱汁。除了酱汁之外，前三样是必须有的，后三样没有也可以。我有的时候还加些甘蓝。酱要最后关火之前放入。
热呼呼的来上一大碗，菜肉都有了，就着新做的白米饭，真是棒极了！
Will Roger’s park is a beautiful park, we’ve been there many times, but this was the first time we hiked it through to the Backbone Trail.
Hard to believe it’s in July. We got a really foggy, cool morning, for a while it was raining a little bit. So even there’s no much shade, it was a very comfortable day for hiking. Many wild flowers are still waiting for us on the side of the well maintened trail. The trail eventually turned narrow and with a lot high grasses on the side when our GPS showing it’s almost 3 miles away from our car. We turned around after it reached 3 miles. The fog got thinner on the way back, so we could see the coast line clearly.
It is a nice hiking trail if you don’t want to drive far.

Stayed in Lone Pine for a really hot Friday night (95F), I was glad to get some fresh air in the mountains. The car drove up a zig-zag shaped road from 3000ft to 10000ft and we got to the parking lot. It was 60F there, which was much cooler than Lone Pine. There were already some people and cars there, some looked like they stayed overnight in the camping ground.
The meadow was beautiful with clear creeks. Golden trout are protected here. Leaving the peaceful meadow behind, we walked through a very steep part covered by forest formed by pines. I had to walk extremely slow because the high altitude. When getting close to the peak, I got some headache but not so bad. It was cold up there, we still saw some snow patches. Finally we got up to the Trail peak, 11605ft. The big mountains with snow close by gave a great view. You feel like they are saying “we are the greater mountains”.
The round trip was 7.5 mile and 2000ft elevation up according to our GPS.

To our surprise, there’re quite a lot wild flowers this spring in death valley national park. And also many types of them, which we’ve never seen in the state parks in Los Angeles.
Among them the most attractive one is this red cacti flower.
