Congratulations! Retirement's nice,... after all those years with little time for family, friends, or even oneself, you suddenly find, you no longer have any time for work!!!
With great health, I opted for a dramatic change in lifestyle, in spite of low budget. My home is completely paid for,.... a 34' rolling upstairs apartment, that often sees changing sights, locals, scenery and seasons, . Living year around in a motor home isn't for everyone, but it's been very accommodating, and comfortable for me. It has all I need or want,... except a garden, and I since I have plenty of time, I often assist others in their gardens as I visit. My 'mini-garage' is equipped with wrenches, hand-tools, power-tools, portable workbenches, even a welder that's often useful.
I have my tv, computer, phone, gold pans & sluice, fishing gear, kayak, e-bike cruiser (primary transportation when home is sited), and various other hobbies not unlike many others in more permanent residences. Easy to accommodate friends and family for dinners or a vacation together, or jus hang out with "Pops" with popcorn and a movie.
And jus because my garage is "micro" and my workshop is under a 20' awning,... doesn't stop me from assorted projects for myself OR others. And like others,... I have an assortment of orphaned wheel assys, forks, pvc fittings, alum, steel, nuts, bolts, paint, camp chairs, and who knows what else one has at home. "Ask grandpa,... he probably has one!" Yup,... check with dad first.
Current major project? An extreme and radical scratch-built e-bike! Inspirations from sites like this, the previous mentioned 'Atomic Zombie', and many others. Stretched hand-crafted rigid square tube frame, powerful rear hub-motor floating in a very fat 16' motorcycle tire that will also support an accommodated passenger, and of course the signature 'outlaw' style of a retired old man that jus won't grow up!!!!
Lookin forward to cruisin' winter in Florida once again,... that's where retired "snowbirds" migrate to.
