I'm really lucky, because when Gary and I got married in 1993 we got rid of pretty much everything we couldn't take with us and hit the road in the RV. We drove from New York to Seattle, then up through BC to White Horse in the Yukon, then back down to Seattle, San Fran, Southern Cal to Lake Havasu in AZ, through TX (with a couple stops for a few weeks here and there), Lafayette, LA, various places in Florida.
We ended up doing contract research, so we were able to continue living in the RV and travelling all over the country until 2001 - when the nature of our business changed a lot. Both the terrorist attack on the World Trade Center and all the business scandals. So we hunkered down then (started rescuing cats, lol!) and then moved into our house in 2004. Had to be within driving distance of NYC (where the bulk of our customers are) - so we're in Northern NJ.
But we went fishing up in Little Atlin Lake at the top of British Columbia. There was no one else there. And mom Bald Eagle was teaching a baby bald eagle how to scavange dead fish (they are scavangers). It was the wildest thing. And when we were packing up the boat (a 10' inflatable quicksilver with a 4 hp motor), the baby grabbed a fish near the boat landing - like 20' from us. Mom was screeched at something, and it was just one of those moments you can't ever forget. It was like watching a National Geographic special - but live and close up!
We also stayed at a place in Orange Lake, FL for over a month. A turtle made a nest under our bus. We were about 100 yards from the lake - and on the shore of the lake, to the West, a bald eagle had a nest, and to the right, an Osprey had a nest. We spent hours just watching either of them come and go, or hunting off in the distance.
We were out fishing one day, and we got to watch the Osprey spiral so high we had to use the binoculars to see it. It started to DIVE - and it bombed the lake - and flew out of the water with a large fish in its claws. Meanwhile, the Eagle had been hovering off to the East (sun at its back), and it dive-bombed the Osprey - which, of course, dropped the fish. The Eagle then grabbed it.
I started bird watching for fun when I lived in NYC (there was a pair of Red-Tailed Hawks nesting on Woody Allen's condo during the Sun Yi fiasco). But the trip(s) around the country for 7+ years in the RV provided some amazing bird (and other animal) watching.
