     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Applicant&#39;s novel stadium seat tray will be described by referring to FIGS. 1-6 of the drawings. The stadium seat tray is generally designated numeral 10. It has a tray portion 12 and an arm portion 14. 
     Tray portion 12 has an outer wall 16 with a top edge 17. The top surface 18 of tray portion 12 has a front recess 19 and a rear recess 20 formed therein. These recesses have cylindrical walls 21 and 22 respectively for receiving drink or food containers therein. Front recess 19 has a bottom wall 24 and rear recess 20 has a bottom wall 25. 
     Arm portion 14 has a top wall 28 with side walls 29 and 30 extending downwardly from its lateral longitudinal edges. 
     In FIG. 2 the stadium arm rest assembly 34 is illustrated in cross section. Stadium seat arm rest assembly 34 has a horizontal arm rest portion 35 having a longitudinally extending x-axis. A brace portion 36 extends vertically downwardly from the the x-axis. Lips 38 and 39 extend inwardly from the respective side walls 29 and 30 and the top of these lips engages the bottom surface of horizontal arm rest portion 35. A recess 40 is formed in top wall 28 and its bottom surface engages the top surface of horizontal arm rest portion 45. 
     An alternative structure for the arm rest portion is illustrated in FIG. 3 and it is generally designated numeral 44. It has a top wall 45 and downwardly extending side walls 46 and 47. A longitudinally extending channel 48 is formed in the inner surface of side wall 46 and a longitudinally extending channel 49 is formed in the inner surface of side wall 47. The opposite ends of horizontal arm rest portion 35 are captured in these respective channels 48 and 49. 
     A second alternative structure for the arm portion is illustrated in FIG. 4 and it is generally designated numeral 50. It has a top wall 51 with downwardly extending side walls 52 and 53. Spring fingers 54 and 55 are formed on the bottom of the respective side walls 52 and 53 and these extend upwardly and inwardly with their top ends in engagement with the bottom surface of horizontal arm rest portion 35. Top wall 51 has a recess 57 formed in it and its bottom surface is engagement with the top surface of horizontal arm rest portion 35. 
     In FIGS. 5 and 6, an alternative arm portion 60 is illustrated. It has a top wall 61 with downwardly extending side walls 62 and 63. Slots 64 and 65 are formed in these respective side walls. A U-shaped adapter member 70 is utilized with this configuration and it has a top wall 71 with downwardly extending spring fingers 72 and 73. On the outer surface of these respective spring fingers are formed tongue members 74 and 75 respectively that mateingly engage with slots 64 and 65.
