In reply to Graeme G and Dave HK:
The weather was exceptional this weekend which likely made things a lot worse.
Just stay away from the honeypots and trade routes up hills and you'll likely be fine.
If you're heading someplace where there's limited parking get there early and be prepared to revert to plan b, c etc.
This summer too many folks have plan a only and then park like Muppets which have resulted in a bunch of parking bans in Perthshire.
