i think with your tripod reaching until your chest height, and together with the height of your dslr, bending abit shouldnt be a problem.
yeah i bring around a tripod too for night shots. i guess at the start in some ways you may be concerned over others looking at you etc. etc., but you gotta get over it, because even when you take a dslr out and shoot without tripod, some people will also look at you. if so, does that mean you should never take your dslr out to shoot at all, because u worry people are looking? anyway, those people are either just curious and will turn away in a couple of seconds, or they are fellow photographers who wants to peep at the gear you're holding ... haha
