What's your limit?
 

When it comes to riding what is/are your limit(s) Limit defined as those things that keep you from riding at given times for example, night riding, rain, snow, arthritis or other medical conditions, length of the ride, heat, city/hwy slabbing, riding solo, riding in groups etc...

Night
Frost
Rain
Solo - minus commuting to work, though I did get in a short stint a month or so ago after work.
Heat - if it means my bike will have to bake in the sun... don't like that and won't ride those days.

What's wrong with a little snow riding???

Due to so much work and school I usually don't ride if I see rain, plus I work outdoors and don't dig getting wet on the way to work and then staying wet through work to be wet at school.

Dark, Rain, and windy is about the only thing that will cause me to pull over if it's too bad

The fact that I couldn't get out of my drive and if I did I wouldn't make it out upright. There is generally a sheet of ice at the bottom. It is quite a challenge getting in and out without sliding into the ditch.

That wasn't directed at you. Though getting out of my hood is a biatch. My drive has a short steep spot at the end which gets very slick (but fun to jump on the motorcycle). My neighborhood hill is pretty steep and during ice storms we are going nowhere.

But sometimes you have to man up...

Ok. But still, I would be nuts if I did try to go out. Actually that would just be plain stupid, IMO.

High winds and temps above 100 during the day.

cash. (or lack thereof)

Exhausted and add two from the following.

Cold

I can deal with two, but not 3
