When I started camping again 10 odd years back I was still running a business which meant I was on call 24/7. Chose a campground near public transport in case I needed to return to the city solo and ensured there was good tower service nearby (well at least for Verizon; took AT+T 3 summers to install a tower but I've access to service from both of them). Allowed me to sit around the campground and conduct business just like I was sitting in my office for the most part. Think I only had to return home once in all those years.
Sometimes technology really is your friend:).
