>>237203It's a false dichotomy.
If the trip I'm taking is about the TRAIL, I'll take a tarp. I can see a few more miles with less weight on my back
If the trip is about the DESTINATION, I'm more likely to take a tent. If I have to be at a specific location like a lake or a hunting site, I might not be able to find an ideal tarp site. I don't spend the evening on foot looking for a spot sheltered from wind, out of a thermal sink, away from bugs, etc.
So it's like this:
Hiking the PCT -Tarp
Fishing a Mountain Lake - Tent
Monitoring the bird species in a field (work) - Tent
Solo weekend trip exploring some new area - Tarp
