David, My recent conversations with POTA activators show mobile (from car or truck) operations are very common. Many parks (Espies. National parks) have restrictions about any wires touching trees, or even spikes in the ground. For this reason many operators are operating mobile HF stations, or semi-mobile. For example One setup I use is a Buddi-stick vertical whip which can be set in 5 minutes after parking a car, attached with a HF mag mount to the roof. This way you can quickly break-down when ready to leave and remove the antenna. Look into how crowded the park will be you have in mind, and the potential to use radials, wires in trees, etc. Crowds and regulations in a particular park can have a big impact on what antennas are possible. Personally I like the convenience for POTA of HF mobile. For SOTA, I like light weight end fed wave wave wire antennas, ideally cut for the band of use. In the woods, after a deep hike there is usually enough space and lack of crowds to throw a wire in the trees near the summit. 73 Glenn KW4TO
