One of the founding principles of Howtomakeadollar is that any time you can get something for free, you should get as much of it as possible, no matter what it is. This is different from hoarding because hoarders take stuff and keep it, while we take stuff and sell it.
I was thinking of this the other day while I was out hiking and saw like 50 toads. I don't know what the market is like for toads nowadays. I suspect it is fairly flat, but a flat market is still a market, and toads are free. So you may as well wrangle a bunch of them together and try to sell them off. A good rule of thumb is that if someone offers you 50 of something for free, then there has to be a way to make money off it. It doesn't really matter what it is. 50 of anything is a good deal.
I did not stop to collect the toads I encountered because I was going hiking and had not brought a proper toad receptacle with me. However, if you want to pursue this opportunity, I will tell you how to do it. First, I was hiking a trail in New Hampshire known as the Pemigewassett Loop, so you will need to go there if you want toads. Secondly, you should know that the Pemi Loop is considered to be the 2nd most difficult day hike in North America. It is about 32 miles, and climbs 11 mountains, so its not going to be easy. But it is worth it because of all the toads you can get.
All you need to do is hike the loop and bring a large bag or box or something. Everytime you find a toad just grab it and drop it in the bag. I promise you will see at least 50 of them if you do this whole trail. After that its just a matter of finding a buyer. Even if you sell all 50 of them for two cents each, you still make a dollar, and I think a two cent toad is a great deal.
I've even thought of a few selling points for to make.
1. Toads are immortal. On my hike, I accidentally stepped on one, but it didn't die. It just hopped away. A few years ago I ran one over with a mower, and it hopped out the other side totally fine. (seriously). No blood, no guts, no sign of any trauma. This is because toads, like Elvis, never actually die. If this fact doesn't get you a toad sale, I don't know what will. Toads are immortal and indestructible.
2. Toads eat lots of insects. If you get toads, you will never get an ant or termite problem. Just get a bunch of toads and let them roam freely around your house. I recommend at least five toads per room. You will probably need to keep your rooms dark and damp at all times, and maybe get some rotten logs, because that is what toads like.
