I've hiked in a half mile a few times on relatively flat ground and it was not fun.especially if it was not flyable and had to hike gear back out.
If you do it in 2 trips take your battens and basetube on the harness trip and leave the glider bag and the padding in the car for the hike.
Even driving to launch can be rough sometimes
I've gone on many miles of REALLY BAD dirt roads and had many flat tires,gotten stuck in mud and had several dents and scratches to the car.
What we do for the love of flight
