Non-Transaction inside a Transaction

I am trying to log a caught exception to elmah while inside of an open transaction.  I have created another transaction to do this, but I am not sure if this is the best route or if I am using it correctly.  If I do not create another transaction and an error occurs the caught exception will be inserted using the transaction and will be included in the rollback.  Is this ok or is there a better way to do it?
try
        {
            using (TransactionScope ts = new TransactionScope())
            {
                sqlCon.Open();

                try
              &nb ...
