Here's a link to the ARRL band plan: http://www.arrl.org/FandES/field/regulatio...andplan.html#2m
As you can see 146.52 is the National Simplex Calling Frequency, meaning that it should only be used to initiate contacts. 146.55 is also within one of the designated frequency ranges for Simplex communication, and has become popular with chasers over the years (although it's not exclusively reserved for chasers).
I always monitor both; however I also usually have a map with the various repeaters available for a given area (along with information on those that you shouldn't come up on during a weather situation).
Perhaps this is also a good time to plug the excellent "kBrews Storm Spotting Frequencies" website... anybody who caries a radio or scanner with them should have this site bookmarked. http://www.caps.ou.edu/~kbrews/spotfreq/index.html
