And I know no amount of that sort of interpretive is going to, you know, is going to be optimum in terms of making sure that people understand what is, who’s trying to do what an exhibit’s trying to tell them. It’s a real challenge. Did you find that your technical interpretive, you mentioned screens and things stood the test of time or were they constantly being fixed, Constantly hammered Yes. By the, by the, by the group of teenage school kids who happen to come around showing off to their friends. No, you’re absolutely right. And, and because not only zoos I, museums and other institutions have a real, real issue. And the trouble is the more sophisticated they are, the more they tend to get, well, not only broken, but of course maintenance on them and so on is, is considerable. I don’t, I mean I, I, there probably are zoos that have maintenance staff capable of dealing with these more sophisticated interpreters, but I know we didn’t have that, the London would’ve been way my years at long way before some of these techniques were developed.
