Hello Molly, welcome to the steem blockchain. I don't know if you like photography or not, but there are a lot of us backyard photographers on steem. A few tags that may be up your alley so to speak if you like photography is #mountainmonday, a tag where we share some mountain picture we took from our backyards or on vacations, no stress fro vying for an award or anything, also #wednesdaywalk, where people just go out for a short 5 minute or so walk and take some pictures of what they say, backyard walk or city town country walk, it's mostly about the short walk and what we saw, #featheredfriday, kind of like mountainmonday only all about our feathered friends, and there have been some absolutly gorgeous pictures shown, and then there is #bouldersunday, all about the big rocks, a lot like the other tags, none of them are really completions or have prizes other than some nice people upvoting the post people share. There is a lot of things to see and do on steemit, I am sure you will find many other places, and not everyone here is a 20 something year old, a lot of us are older and retired.
