I love all the KleinClark races I've run (4 total). The Palm Springs Half is great. The weather is always perfect: a bit cool to start but by the time the race is over it can get up to 70 degrees. The on course support is great, as there is a stop every mile or so. The course is pretty flat, though there are a lot of false flats throughout. Most of the course is pretty scenic but there are a few dull parts in the middle. Coming and going isn't an issue as there is plenty of parking. There is no real expo but this isn't an issue for me. Also, in the past the long sleeve tech shirt was much nicer than the 2015 version.

[Edit: This race has been moved from Palm Springs to Palm Desert, and is now in January rather than February, so the review is likely no longer relevant]
