         [0003]     2. The Prior Art  
         [0004]     Background  
         [0005]     In the construction industry a need for a portable plan table is readily apparent. Prior to the present application, contractors, laborers, architects, surveyors and others on a construction site or a land parcel being surveyed carried plans in their hands using whatever surfaces were convenient to make notes on their plans. Further, the plans are rarely spread out and only a small portion of the plans is readily visible to the user. Further, because of the rough handling the plans received on those surfaces they rarely held up for long. In so doing the present application resolves some of the issues by providing a plan table, surveyor&#39;s table or drafting table on which the plans may be fully extended and visible. Further, the plan table may be mounted to a truck or on a rolling base which may be wheeled about the construction site.
