All the trails around me contain at least one, two foot drop, one of them also has quite alot of 4ish ft drops (they're actually just a few rooty stepdowns, but I prefer to jump them).
What is worrying me more though, is the trail that I'm starting to ride more has a freeride park half way round, and you can take a detour onto quite a jumpy downhill course at the end.
Anything which I see when riding which is 5 ft or under though I'll quite happily try riding off.
