solo flight to Oakdale

I flew by myself from reid-hillview in San Jose to Oakdale which is east of Stockton which totals to 140 nautical miles. I got lost on the way going to Oakdale because it was so hazy and the visibility was awful even though the forecast said it was sky clear. So I spent nearly half an hour looking for the runway, good thing the navigation instruments work, and I was able to use it to find my location on the chart. I was very south because I kept thinking that the runway will be on the right side so I kept going right and passed the runway on my left. I'm glad that I finished my 5th solo flight. I need to fly more to get more confidence and experience.
