single track can be a blast and my guess is you would enjoy
might depend on the areas where you can ride - start easy and progress from there
maybe start with a combination of dirt roads and some easy trails
areas you might want to limit or avoid - and / or push through :
> rocks - some scattered rocks might not be an issue - but extremely rocky areas / rock gardens can be a real challenge
> extreme climbs and descents
> extreme mud
> winter riding with frozen ground / snow / ice
> tree crossings - small trees not too much of an issue but larger trees can be a real challenge (dismount and lift / carry bike over)
> exposed roots - most times not much of an issue but larger roots can be a challenge especially when wet (and more-so if you cannot square up to them)
> extreme rutted sections can be a challenge
probably more I cannot think of at this time
