A lot of information (possibly too much to take in during one tour). The guide (Don) was very nice and informative, but really needed to take some time to breathe, literally. The constant speaking was a bit stressful at times - I even overheard someone say, just after the introduction, that she "needed a drink". A speaker is needed. Without such the guide has to yell and I, for one, found his yelling a bit taxing and stressful. A speaker would also be great during the walking portions of the tour because when the guide turns his head (and his mouth) away from the group it is nearly impossible to know what he is saying. I came away from the tour with a better knowledge of the city in which I live (which was my goal), but I have to be honest - I thought about losing the group and calling an Uber back to my car a couple of times. Sorry, Don. You offer a great insight into the city and your knowledge is outstanding, but please work on your presentation (maybe talk a bit less so people can take it all in) and you will have it in the bag.
