I'm not calling this theory bullshit or anything, because I've had awesome highs while on walks, rides, and even while just exploring shit around a house. However, you do have to consider the fact that if you do get up and moving too much while high, you usually won't be as high for quite as long. I'm not saying that people shouldn't get up and explore while or after blazing, but it is a bad idea to over do it, just like eating too much when you're stoned.
