Whats Your Favorite Offline Niche For Prospecting?

I Thought it would be interesting to find out what other marketers favorite offline niches to target are. I know there is a thread for niches that make $1000 or more and that's useful but I think that's different then taking a poll of what peoples favorite to target is.

So to start with myself, I target multiples for 1 main city and I place them all into one spreadsheet then import them into my crm of choice. I then sort out the ones that I feel would be the best wins and put them into a top 100 group and target those.

So here are my favorites

#1 Lawyers: I know others on here don't like them but I find the gatekeepers forward me to the DM or the person in charge of marketing without any hassle at all, I also don't worry if they can afford me. They also are well aware of the need to market themselves and have fierce competition so they don't mind spending money on it.

#2 Roofers: I like them because its a 50/50 chance they will answer directly and you can by pass the gatekeeper entirely.

#3 Chiropractors: Although probably the most difficult of the 3 to get to the DM from cold calling. I like them because they won't turn into a PITA customer and rarely make requests and just simply pay on time and don't ask for much, and they can also afford me. They however are more difficult to get to and the gatekeepers are more reluctant to let people through, but once you win one as a client they are gems and great sources for referrals as are lawyers.

So those are my favorite 3 niches, eager to hear others favorites.
