I live on the corner end of an apartment and it's right by a city owned fire lane. This corner is a nice discreet spot for younger people to hang out and smoke weed at. This area has become a non stop hang out zone and due to it technically being on city property, the management won't do a single thing about it.. The coughing from the weed smoking is unbearable and I've had enough. Besides that, I really like the place and area and I'm really not in the mood to move right now. Plus I might be owning it eventually. I'm thinking that I'll just make it difficult for people wanting to hang out there. If I put some nasty or sticky crap where people would normally be standing, well maybe that could work? It rains a lot here so I'd need to use something rain proof and something that won't stink so bad, that the smell travels right up to my windows. I wouldn't want to use something that's going to kill someone's dog too. Any ideas?
