Had a thought...tell me if this sounds like a bad idea. First, some data points/assumptions:
1) At any given time nationally anyhow, 40-50% of people want to leave their job because they don't like it, feel undervalued, aren't satisfied, low pay, etc... So the pickings are there, we just need to lure them.
2) I think we have a relatively higher job satisfaction rate...its a great job, if the money is there.
3) I go to the gym a couple nights per week. See a lot of the same faces, but don't really know anybody. Certainly don't know what they do for a living.
4) I'm thinking people going to the gym on a regular basis would prefer a physically active job.
5) People dedicated to going to the gym are less likely to be stoners who cannot figure out how to show up.
(maybe I'm doing a lot of projecting here, because I know me pretty well and, of course, all reasonable people think like me!

)
Anyhow, to the point: Is the gym a good place to recruit workers? Probably not experienced tree workers...but I'm OK with that. If somebody wants to be active, work outside, and is willing to learn, I can get them there.
If so, how do I connect? I'm not a real outgoing guy that's going to strike up conversations with people wearing earbuds working out. That's pretty much everybody and I take that as a hint "I don't want to talk to you". So I get to thinking: "how can I invite conversation about tree work with the right people?" I need them to ask me. How about I make up some t-shirts with corny puns about tree work to see if that leads to people asking me about a job:
Most jobs are boring
Working on trees is Arboring
Wood you like to work outside?
Ask me how.
Leaf the ordinary below and climb trees.
Pining for a new career?
The trees are calling!
(would people whose second language is English get some of those?)
thoughts?
