I typically skip shows at the Hollywood Bowl for this reason - it's too difficult/expensive to get up front and the back of the venue is full of people having picnics, drinking wine and largely not giving a shit haha. I've seen a few shows at Red Rocks and have def found the further back you are the less people care but that is pretty standard, especially when it comes to big historic venues. I think you should be safe being up front though. Red Rocks in general is not nearly as bad with talking and general not giving a fuck as The Bowl in my experience but I think that has to do with the fact that Colorado just has better crowds than LA (which are the worst in the country imo).
I have tickets for Friday but am currently looking for Saturday so if anyone has an extra pair they are looking to offload I'd be happy to take them. Have an extra pair for Raleigh I could trade if there was interest.
