The AGP Tour website templates were probably one of my tougher challenges. Not only where there 10 specific page templates in total (based on a client provided design), but several required the use of equal height columns which even with the jQuery plugin can be a bit vexing. All told I think this site came off very well, there’s a lot of great variety of content there, and the effort involved really shows.
I think the challenging projects can be the most rewarding – balanced equally among several easy jobs of course.
