I have nothing but respect for those who decide to re-home an animal after doing proper research, trying their best, and admitting things just aren't working out. I've seen this type of thing happen before with horses (which can also be scary and dangerous when things aren't working out), and it's always a relief to see both owner and animal move on to better partners. You did well by Wallace and put in far more effort than most other people would have in your situation. Props to you for that and finding him a good new home.
Thank you for sharing your journey with Wallace - it's not often that people honestly share experiences like yours in this hobby. If it's any consolation, your story (and others', such as bcr229's) has helped me keep my screen name from becoming an unfortunate reality. I think the amount of SD buyers' remorse around here is very telling -- as one carpet breeder put it to me, a 6' retic is a 6' retic. No matter how small the retic is, it's still an active, advanced-level animal. I've personally come to realize that they're more than I'm long-term prepared/willing to deal with and that they're just not the snake for me, no matter how much I love them. So, thank you again for sharing your story - it's helped keep a similar one from coming about.
