Part of the problem may be to do with availability of aircraft too.
Lets face it....there are only so many places you can go on a 1.5 hour round trip. More than that, and you must stop somewhere, at least for a couple of hours, if not over night, simply to justify the cost.
Unfortunately many clubs don't like you taking an aircraft away for much longer than it will be flying...and even if they do, you have to book way in advance to get it free for a day or two.
Which leaves many renters running out of new and interesting places to go fly to.
