Continuity mistake: At the start, there's a long shot of the Land Rover driving down a long stretch of road towards the camera and then passing it. That road, landscape, and mountains are very distinctive. As Roy, John, and Chet continue talking and driving, when they reach the scene of a traffic accident, Chet sets up a flare behind the Land Rover and another flare behind the pickup truck, then Chet sees a car coming from the direction which the Land Rover was headed. The problem is that the road/landscape/mountains shown earlier in the long shot of the Land Rover, which had been driving from the opposite direction, is the same that's shown here, as Chet tries to stop the car. Then to top it off, when Chet first notices the second car in the distance, it's coming from the opposite direction of the first car, but once again the view is exactly the same.
Continuity mistake: When Johnny, Roy, and Chet are at the site of the traffic accident, during this scene the shadows' lengths - from long, to short, back to long, and its directions keep changing drastically. Such as when Chet stands in the middle of the road, looking in the direction of the vehicle with the siren, his long shadow is cast to his left, but the oncoming vehicle also casts a shadow to its left (even though it's heading towards Chet), then in the next shot that vehicle's shadow has moved to its opposite side.
Continuity mistake: When Johnny adjusts his IV after the snakebite, he tells Captain Stanley that he's ready to leave, and Chet is not wearing his helmet, but in the next shot as Marco heads for the squad Chet is wearing the helmet.
Continuity mistake: When Johnny is bitten by the rattlesnake he's holding the handie-talkie, but then he drops it and the HT falls to the other side of the car, as he hoists himself up against the car door. However, when he sits down on the ground he is still holding the handie-talkie.
Continuity mistake: When Station 51 is dispatched to the car over the cliff at Bear Mountain, the timeout is 08:12, then when Roy contacts Rampart his watch reads 6:55. When Johnny checks the girl who can't see, his watch reads 12:45, but when Johnny contacts Rampart his watch reads 6:05. Then after the snakebite, when the guys carry Johnny to the back of Engine 51, Johnny's watch reads 10:35.
Continuity mistake: At the scene of the traffic accident, when Johnny tries to calm the woman who cries that she's afraid, it cuts to a shot of Chet as the camera pans to the left, and we see the position of the pickup truck on the road. When they hear the siren of help coming, Chet stands in the road directing the vehicle, and the pickup is not where it was in that earlier shot, it's now much farther down the road.
Continuity mistake: At the start, there's a closeup of Roy, Johnny, and Chet, and it cuts to a long shot of the landscape around them while they're driving, then it cuts back to the closeup. The landscape the Land Rover passed in the long shot is entirely different than in the previous and following closeups.
Continuity mistake: When Roy and Chet go to Rampart to visit Johnny on their day off, Dixie tells them that Johnny's in room 205, but when Chet and Roy walk in the number on the door is 230.
Continuity mistake: When Chet flags down the young driver to get help for the traffic accident victims, the driver's side wing mirror is tilted out at a wide angle in the long shot, but in the next closeup the wing mirror has been pushed flat up against the car, so as not to block the actor during the conversation.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
