There are a couple of different ways to ride over logs, but it all comes down to its size. For small logs (say ankle height) I find it easiest to pop the front wheel over and let the rear wheel roll over the log.

For logs that are a little bit taller you will need to lift the front wheel first and then shift the weight forward to lift the rear wheel.

For really big logs, where the chain ring hits, instead of lifting the front wheel over the log you need to lift the front wheel on top of the log and then perform a quick bunny hop (lift both front and rear at the same time) to lift the front wheel off and put the back wheel on the log. Now this is really hard to do and it is something that I am still learning myself.

I honestly think log overs are the hardest thing to master in mountain biking, but the more you practice the easier it becomes. I often put bricks out on the back lawn to practice.

And C after the next state round there is a 4 week break before the next race so I am more than happy to come out for a ride with you one weekend and teach you some new tricks.
