Networking was what really got me to do a deep dive into technology. Circa 2002, I really really wanted to LAN Party with my neighbor across the street remotely but neither of our 802.11b routers could reach. We spent so much time reading about how to do this and we ended up building a pair of Pringles can antennas on WiFi extenders, and long ethernet cables running through our yards into our bedroom windows, which ended up working great.
Fun memories. Networks are cool.
