If you're looking for a no-hassle, peaceful place to put your rig for a night or two, you can park in front of my house near Downtown Littleton. Our street is super mellow and peaceful. I can't promise a lot of interaction because I have a jealous dog (who will remain inside) and renters who share the house. However, you will be welcome to park your rig in front of the house with no worries.
No smoking, weed, Jules or tobacco
You can park on-street or in the driveway, if my rig is not there already.
We do a lot of last minute trips in the summer, but feel free to make a request to see if we can accommodate you.
Historic Old Town Littleton is a nice 10 minute walk -- shops and restaurants. Cornerstone Park is two blocks from my place for a chance to walk around and stretch your legs. Pirates Cove (a big pool with LOTS of water features) is about a five minute walk.
