I can see for a fact that rainbows end on the ground, with my own eyes, but whenever I chase it I'm always a second too late, can anyone tell me if they've actually made it to where a rainbow meets the ground and if so what's it like? I reckon it must be a surreal experience.

What kind of cactus do I have?
http://good-times.webshots.com/photo/2747942920099979390GFnXpY

I've had this cactus for 5 years, and would like to know what I have. The internet has failed me and I haven't been able to figure it out on my own by googling things.

When I first got the cactus, it was smaller (it's still small) and over the years not only has it grown overall, but it's sprouted a ton of smaller versions of itself all over. It grows flowers like mad during the summer.

All of it's "babies" or whatever those are seem to be crowding the cactus around the base. Should I be removing them?

I use to think lions were, but I read tigers take them down easily. Then I read that grizzly bears are just so massive, a tiger is no match for them. What animal is the beast of all beasts?
