Aerodrome is a 3 column template that comes with modifiable and transparent background image, so you can choose an image that suits your blog theme. The template has two navigation bars - above and below the header - and nowadays many templates come with this feature.
The header comes with an ad space and RSS icon on the extreme right. The main post structure is designed in the form of separate boxes for each post, with the date stamp and comments appearing separately on the left.
While the second column also contains ad space, although the second and third columns are a bit narrow and have fixed width. The third sidebar is transparent, which gives a nice effect to the theme.
