Welcome, Cygnus !
A 12" scope can be useful in a light polluted area, as long it is transportable.
When you can dismantle it quickly, put in in your car and drive to Blue Mountains or even closer (e.g. Springwood) and stay a weekend there, you have lots of fun with the galactic center almost overhead in mid winter.
When you have a wheel cart, you can move your Dob easily through your backyard.
I have made such a cart for my 16" Dob.
