^^^ nice
is it close to your size? stand over the top tube. you should have an inch or two clearance between the tube and your parts.
- air up the tires, check to see if they're really dry or ok and if the tubes are rotten. garaged the whole time?
- clean and lube the chain
- turn it upside down resting on the seat and bars and spin through all the gears while turning the crank
- clean the rims
- check the brakes; adjust as necessary
all the info you'll need is out there on the interwebs. somebody here will probably suggest a favorite maintenance site. search for the name "sheldon brown".
if everything seems ok, hop on and spin around the neighborhood. raise/lower the seat for comfort. ride more.
have fun.
