I stepped into them a lot. Some people find it difficult to look before every step they take. I cannot do that. Blooming time is long and playing kids pay less attention to their surroundings.

Edit: like 5 times. Which is an issue if you stop being able to walk after you step into them.

Clover sucks if you got children that step of the bees.

Every approach is inefficient. Gotta pick your losses. You have to keep in mind scalability (how many parts can be bought at what volume at what price). In particular if you are not planning many years ahead.
