You don't tell the season, but a picnic in the park, or beach if the weather is good.
You should have a big BBQ in the garden if the weathers good and have an all day drinking session. Pretty much just have a summer garden party and if you want it to be really cool, get a freakin slip n slide!!
What does a garden have to do with anything? Go out drinking. Hire a couple prostitutes. Have a battle royal, last man standing gets a 100 dollars.
Any ideas got to be relatively cheap also I have a large garden
