If you aren't growing it, you can find it at the grocery store or, better yet, at an organic market. Asparagus doesn't have a very long shelf life, in fact it's best if you eat it the same day you pick it, so you need to be careful to choose stalks that are firm. Store them in the fridge with a moist paper towel around them if you can't use them all at once.
Some people don't like asparagus because it smells like urine when you boil it. The trick to avoiding that problem is not not boil it. It's tasty raw, lightly sautéed, or grilled. The key is to not overcook it. Asparagus is best still a bit crisp.
I'd like to thank Paul's Farm Fresh Produce for the wonderful fresh asparagus, broccoli, and pecans used in the photo shoot. I'd also like to thank the butcher at Mike's Market for cutting the breakfast steaks just the way I like them. The meal was delicious.
