A few people in my neighborhood have fences/walls. Most are those incredibly ugly white plastic things. I know where my corner markers are. I try not to put stuff beyond my boundary, but it generally doesn't really make a difference as three sides of my property is wooded/wild, and I'm probably the only person to go in there. The town "owns" 10' on either side of the road in front, so I try not to put much there except for my mailbox and a couple of small flower patches. Note: Kids do not recognize boundaries. They will ride their bikes on my driveway, across my yard, wherever they feel like it. Smart people, those kids.
The best times were back in the early '90s when we were just five guys coding and playing music and smoking bongs and playing Quake after hours and maybe getting paid this month. By the dotcom implosion and 9/11, we had an award winning retail product, the first single-shopping cart online mall, 70+ employees, and we'd moved from the old house through several iterations of office spaces. But a bunch of yahoos from Montreal had bought us, and brought everything crashing down. The old days are calling.
Trump should be allowed on twitter only if he can only interact with an army of sycophantic bots. No real people should be able to follow him or read his spewings. COVFEFE!
